Tsunami and Love Canal

A  tsunami  (‘harbor wave') or  tidal wave  is a series of water waves (called a  tsunami wave train) caused by the displacement of a large volume of a body of water, usually an ocean, but can occur in  large lakes. Tsunamis are a frequent occurrence in Japan; approximately 195 events have been recorded. Due to the immense volumes of water and energy involved, tsunamis can devastate coastal regions.Earthquakes,  volcanic eruptions  and other  underwater explosions  (including detonations of underwater  nuclear devices), landslides  and other  mass movements,  meteorite ocean impacts or similar impact events, and other disturbances above or below water all have the potential to generate a tsunami. The  Greek  historian  Thucydides  was the first to relate tsunami to  submarine earthquakes,  but understanding of tsunami's nature remained slim until the 20th century and is the subject of ongoing research. Many early  geological,  geograp hical, and oceanographic  texts refer to tsunamis as â€Å"seismic sea waves. CHARACTERISTICS: While everyday  wind waves  have a  wavelength  (from crest to crest) of about 100  meters (330 ft) and a height of roughly 2  meters (6. 6 ft), a tsunami in the deep ocean has a wavelength of about 200  kilometers (120 mi). Such a wave travels at well over 800  kilometers per hour (500 mph), but due to the enormous wavelength the wave oscillation at any given point takes 20 or 30 minutes to complete a cycle and has amplitude of only about 1  meter (3. 3 ft). This makes tsunamis difficult to detect over deep water. Ships rarely notice their passage.As the tsunami approaches the coast and the waters become shallow,  wave shoaling  compresses the wave and its velocity slows below 80  kilometers per hour (50 mph). Its wavelength diminishes to less than 20  kilometers (12 mi) and its amplitude grows enormously, producing a distinctly visible wave. Since the wave st ill has such a long wavelength, the tsunami may take minutes to reach full height. Except for the very largest tsunamis, the approaching wave does not break (like a  surf break), but rather appears like a fast moving  tidal bore.Open bays and coastlines adjacent to very deep water may shape the tsunami further into a step-like wave with a steep-breaking front. When the tsunami's wave peak reaches the shore, the resulting temporary rise in sea level is termed ‘run up'. Run up is measured in meters above a reference sea level. A large tsunami may feature multiple waves arriving over a period of hours, with significant time between the wave crests. The first wave to reach the shore may not have the highest run up. About 80% of tsunamis occur in the Pacific Ocean, but are possible wherever there are large bodies of water, including lakes.They are caused by earthquakes, landslides, volcanic explosions, and  bolides. GENERATION MECHANISMS: The principal generation mechanism (o r cause) of a tsunami is the displacement of a substantial volume of water or perturbation of the sea. This displacement of water is usually attributed to earthquakes, landslides, volcanic eruptions, or more rarely by meteorites and nuclear tests. The waves formed in this way are then sustained by gravity. It is important to note that  tides  do not play any part in the generation of tsunamis; hence referring to tsunamis as ‘tidal waves' is inaccurate.Seismicity generated tsunamis Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Tectonic earthquakes are a particular kind of earthquake that are associated with the earth's crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position. More specifically, a tsunami can be generated when  thrust faults  associated with  convergent  or destructive  plate boundaries  move abruptl y, resulting in water displacement, due to the vertical component of movement involved.Movement on normal faults will also cause displacement of the seabed, but the size of the largest of such events is normally too small to give rise to a significant tsunami. |[pic] |[pic] |[pic] |[pic] | |Drawing of  tectonic plate |Overriding plate bulges under |Plate slips, causing |The energy released produces | |boundary  before earthquake. |strain, causing tectonic uplift. |subsidence  and releasing energy |tsunami waves. | | | |into water. | Tsunamis have a small  amplitude  (wave height) offshore, and a very long  wavelength  (often hundreds of kilometers long), which is why they generally pass unnoticed at sea, forming only a slight swell usually about 300  millimeters (12 in) above the normal sea surface. They grow in height when they reach shallower water, in a  wave shoaling  process described below. A tsunami can occur in any tidal state and even at low tide can sti ll inundate coastal areas. On April 1, 1946, a magnitude-7. 8 (Richter scale)  earthquake  occurred near the  Aleutian Islands,  Alaska.It generated a tsunami which inundated  Hilo  on the island of Hawaii’s with a 14  meters (46 ft) high surge. The area where the  earthquake  occurred is where the  Pacific Ocean  floor is  subducting  (or being pushed downwards) under  Alaska. Examples of tsunami at locations away from  convergent boundaries  include  Storegga  about 8,000 years ago,  Grand Banks  1929,  Papua New Guinea  1998 (Tappin, 2001). The Grand Banks and Papua New Guinea tsunamis came from earthquakes which destabilized sediments, causing them to flow into the ocean and generate a tsunami. They dissipated before traveling transoceanic distances.The cause of the Storegga sediment failure is unknown. Possibilities include an overloading of the sediments, an earthquake or a release of gas hydrates (methane etc. ) The  1960 V aldivia earthquake  (Mw  9. 5) (19:11 hrs UTC),  1964 Alaska earthquake  (Mw  9. 2), and  2004 Indian Ocean earthquake  (Mw  9. 2) (00:58:53 UTC) are recent examples of powerful mega thrust  earthquakes that generated tsunamis (known as  teletsunamis) that can cross entire oceans. Smaller (Mw  4. 2) earthquakes in Japan can trigger tsunamis (called  local  and regional tsunamis) that can only devastate nearby coasts, but can do so in only a few minutes.In the 1950s, it was discovered that larger tsunamis than had previously been believed possible could be caused by giant  landslides. These phenomena rapidly displace large water volumes, as energy from falling debris or expansion transfers to the water at a rate faster than the water can absorb. Their existence was confirmed in 1958, when a giant landslide in Lituya Bay,  Alaska, caused the highest wave ever recorded, which had a height of 524 meters (over 1700 feet). The wave didn't travel far, as it st ruck land almost immediately. Two people fishing in the bay were killed, but another boat amazingly managed to ride the wave.Scientists named these waves  mega tsunami. Scientists discovered that extremely large landslides from volcanic island collapses can generate  mega tsunami that can travel trans-oceanic distances. SCALES OF INTENSITY AND MAGNITUDE: As with earthquakes, several attempts have been made to set up scales of tsunami intensity or magnitude to allow comparison between different events. Intensity scales The first scales used routinely to measure the intensity of tsunami were the  Sieberg-Ambraseys scale, used in the  Mediterranean Sea  and the  Imamura-Iida intensity scale, used in the Pacific Ocean.The latter scale was modified by Soloviev, who calculated the Tsunami intensity  I  according to the formula [pic] Where  Hav  is the average wave height along the nearest coast. This scale, known as the  Soloviev-Imamura tsunami intensity scale, is u sed in the global tsunami catalogues compiled by the  NGDC/NOAA  and the Novosibirsk Tsunami Laboratory as the main parameter for the size of the tsunami. Magnitude scales The first scale that genuinely calculated a magnitude for a tsunami, rather than an intensity at a particular location was the ML scale proposed by Murty & Loomis based on the potential energy.Difficulties in calculating the potential energy of the tsunami mean that this scale is rarely used. Abe introduced the  tsunami magnitude scale  Mt, calculated from, [pic] where  h  is the maximum tsunami-wave amplitude (in m) measured by a tide gauge at a distance  R  from the epicenter,  a,  b  &  D  are constants used to make the Mt  scale match as closely as possible with the moment magnitude scale. WARNINGS AND PREDICTIONS: Drawbacks can serve as a brief warning. People who observe drawback (many survivors report an accompanying sucking sound), can survive only if they immediately run for hi gh ground or seek the upper floors of nearby buildings.In 2004, ten-year old  Tilly Smith  of  Surrey,  England, was on  Maikhao beach  in  Phuket,  Thailand  with her parents and sister, and having learned about tsunamis recently in school, told her family that a tsunami might be imminent. Her parents warned others minutes before the wave arrived, saving dozens of lives. She credited her geography teacher, Andrew Kearney. In the  2004 Indian Ocean tsunami  drawback was not reported on the African coast or any other eastern coasts it reached. This was because the wave moved downwards on the eastern side of the fault line and upwards on the western side.The western pulse hit coastal Africa and other western areas. A tsunami cannot be precisely predicted, even if the magnitude and location of an earthquake is known. Geologists,  oceanographers, and seismologists  analyze each earthquake and based on many factors may or may not issue a tsunami warning. However , there are some warning signs of an impending tsunami, and automated systems can provide warnings immediately after an earthquake in time to save lives. One of the most successful systems uses bottom pressure sensors that are attached to buoys. The sensors constantly monitor the pressure of the overlying water column.This is deduced through the calculation: [pic] Where, P  = the overlying  pressure  in Newton per meter square, ? = the  density  of the  seawater = 1. 1 x 103  kg/m3, g  = the  acceleration due to gravity = 9. 8 m/s2  and h  = the height of the water column in meters. Hence for a water column of 5,000 m depth the overlying pressure is equal to [pic] Or about 5500  tonnes-force  per square meter. Regions with a high tsunami risk typically use  tsunami warning systems  to warn the population before the wave reaches land. On the west coast of the United States, which is prone to Pacific Ocean tsunami, warning signs indicate evacuation routes .In Japan, the community is well-educated about earthquakes and tsunamis, and along the Japanese shorelines the tsunami warning signs are reminders of the natural hazards together with a network of warning sirens, typically at the top of the cliff of surroundings hills. The  Pacific Tsunami Warning System  is based in  Honolulu,  Hawaii. It monitors Pacific Ocean seismic activity. A sufficiently large earthquake magnitude and other information trigger a tsunami warning. While the seduction zones around the Pacific are seismically active, not all earthquakes generate tsunami.Computers assist in analyzing the tsunami risk of every earthquake that occurs in the Pacific Ocean and the adjoining land masses. |[pic] |[pic] |[pic] |[pic] | |Tsunami hazard sign |A tsunami warning sign on |The monument to the victims of |Tsunami memorial | |atBamfield,  British Columbia |a  seawall  in  Kamakura, Japan, |tsunami at Laupahoehoe,  Hawaii |inKanyakumari  beach | | |2004. | | |As a direct result of the Indian Ocean tsunami, a re-appraisal of the tsunami threat for all coastal areas is being undertaken by national governments and the United Nations Disaster Mitigation Committee. A tsunami warning system is being installed in the Indian Ocean. Computer models can predict tsunami arrival, usually within minutes of the arrival time. Bottom pressure sensors relay information in real time. Based on these pressure readings and other seismic information and the seafloor's shape and coastal  topography, the models estimate the amplitude and surge height of the approaching tsunami.All Pacific Rim countries collaborate in the Tsunami Warning System and most regularly practice evacuation and other procedures. In Japan, such preparation is mandatory for government, local authorities, emergency services and the population. Some zoologists hypothesize that some animal species have an ability to sense subsonic  Rayleigh waves  from an earthquake or a tsunami. If c orrect, monitoring their behavior could provide advance warning of earthquakes, tsunami etc. However, the evidence is controversial and is not widely accepted.There are unsubstantiated claims about the Lisbon quake that some animals escaped to higher ground, while many other animals in the same areas drowned. The phenomenon was also noted by media sources in  Sri Lanka  in the  2004 Indian Ocean earthquake. [21][22]  It is possible that certain animals (e. g. ,  elephants) may have heard the sounds of the tsunami as it approached the coast. The elephants' reaction was to move away from the approaching noise. By contrast, some humans went to the shore to investigate and many drowned as a result. It is not possible to prevent a tsunami.However, in some tsunami-prone countries some  earthquake engineering  measures have been taken to reduce the damage caused on shore. Japan  built many tsunami walls of up to 4. 5  metres (15 ft) to protect populated coastal areas. Oth er localities have built  floodgates  and channels to redirect the water from incoming tsunami. However, their effectiveness has been questioned, as tsunami often overtop the barriers. For instance, the  Okushiri, Hokkaido tsunami  which struck  Okushiri Island  of  Hokkaido  within two to five minutes of the  earthquake on July 12, 1993  created waves as much as 30  metres (100 ft) tall—as high as a 10-story building.The port town of Aonae was completely surrounded by a tsunami wall, but the waves washed right over the wall and destroyed all the wood-framed structures in the area. The wall may have succeeded in slowing down and moderating the height of the tsunami, but it did not prevent major destruction and loss of life. [23] Natural factors such as shoreline tree cover can mitigate tsunami effects. Some locations in the path of the 2004 Indian Ocean tsunami escaped almost unscathed because trees such as  coconut palms  and  mangroves  absorbe d the tsunami's energy.In one striking example, the village of  Naluvedapathy  in India's  Tamil Nadu  region suffered only minimal damage and few deaths because the wave broke against a forest of 80,244 trees planted along the shoreline in 2002 in a bid to enter the  Guinness Book of Records. [24]  Environmentalists have suggested tree planting along tsunami-prone seacoasts. Trees require years to grow to a useful size, but such plantations could offer a much cheaper and longer-lasting means of tsunami mitigation than artificial barriers. The Love Canal chemical waste dumpIn 1920 Hooker Chemical had turned an area in Niagara Falls into a municipal and chemical disposal site. In 1953 the site was filled and relatively modern methods were applied to cover it. A thick layer of impermeable red clay sealed the dump, preventing chemicals from leaking out of the landfill. A city near the dumpsite wanted to buy it for urban expansion. Despite the warnings of Hooker the city eve ntually bought the site for the meager amount of 1 dollar. Hooker could not sell for more, because they did not want to earn money off a project so clearly unwise.The city began to dig to develop a sewer, damaging the red clay cap that covered the dumpsite below. Blocks of homes and a school were built and the neighborhood was named Love Canal. Love Canal seemed like a regular neighborhood. The only thing that distinguished this neighborhood from other was the strange odors that often hung in the air and an unusual seepage noticed by inhabitants in their basements and yards. Children in the neighborhood often fell ill. Love Canal families regularly experienced miscarriages and birth defects.Lois Gibbs, an activist, noticed the high occurrence of illness and birth defects in the area and started documenting it. In 1978 newspapers revealed the existence of the chemical waste dump in the Love Canal area and Lois Gibbs started petitioning for closing the school. In August 1978, the clai m succeeded and the NYS Health Department ordered closing of the school when a child suffered from chemical poisoning. When Love Canal was researched over 130 pounds of the highly toxic carcinogenic TCDD, a form of dioxin, was discovered. The total of 20. 00 tons of waste present in the landfill appeared to contain more than 248 different species of chemicals. The waste mainly consisted of pesticide residues and chemical weapons research refuse. The chemicals had entered homes, sewers, yards and creeks and Gibbs decided it was time for the more than 900 families to be moved away from the location. Eventually President Carter provided funds to move all the families to a safer area. Hooker’s parent company was sued and settled for 20 million dollars. Despite protests by Gibbs’s organization some of the houses in Love Canal went up for sale some 20 years later.The majority of the houses are on the market now and the neighborhood may become inhabited again after 20 years o f abandonment. The houses in Love Canal are hard to sell, despite a renaming of the neighborhood. It suffered such a bad reputation after the incident that banks refused mortgages on the houses. None of the chemicals have been removed from the dumpsite. It has been resealed and the surrounding area was cleaned and declared safe. Hooker’s mother company paid an additional 230 million dollars to finance this cleanup. They are now responsible for the management of the dumpsite.Today, the Love Canal dumpsite is known as one of the major environmental disasters of the century. **** Love Canal is an abandoned canal in Niagara County, New York, where a huge amount of toxic waste was buried. The waste was composed of at least 300 different chemicals, totaling an estimated 20,000 metric tons. The existence of the waste was discovered in the 1970s when families living in homes subsequently built next to the site found chemical wastes seeping up through the ground into their basements, forcing them to eventually abandon their homes.Love Canal was used from the 1940s through the 1950s by the Hooker Chemical Company and the city of Niagara Falls, among others, to dispose of their hazardous and municipal wastes and other refuse. The canal was surrounded by clay and was thought at the time to be a safe place for disposal—and, in fact, burying chemicals in the canal was probably safer than many other methods and sites used for chemical disposal at the time. In 1953, the Niagara Falls Board of Education bought the land-fill for $1 and constructed an elementary school with playing fields on the site.Roads and sewer lines were added and, in the early 1970s, single-family homes were built adjacent to the site. Following a couple of heavy rains in the mid-1970s, the canal flooded and chemicals were observed on the surface of the site and in the basements of houses abutting the site. Newspaper coverage, investigations by the State of New York and by the U. S. Environm ental Protection Agency, combined with pressure from the district's U. S. congressional representative and outrage on the part of local residents, led to the declaration of a health emergency involving â€Å"great and imminent peril to the health of the general public. Ultimately, in August, 1978, a decision was made by Governor Hugh Carey, supported by the White House, to evacuate the residents and purchase 240 homes surrounding the site. Shortly thereafter, the residents of nearby homes that did not immediately abut the site also became concerned about their health and conducted a health survey that purported to show an increase in the occurrence of various diseases and problems such as birth defects and miscarriages, which were attributed to chemical exposures.A great controversy ensued over whether the observations were real or reflected normal rates of such problems, and whether chemical exposures had, in fact, occurred. Eventually, political pressure resulted in families bein g given an opportunity to leave and have their homes purchased by the State. About 70 homes remained occupied in 1989 by families who chose not to move. The controversy at Love Canal followed on the heels of the heightened awareness that occurred in the 1960s about environmental contamination, and it contributed to public and regulatory concern about hazardous wastes, waste disposal, and disclosure of such practices.Such concerns led Congress to pass the Resource Conservation and Recovery Act (RCRA) and the Toxic Substances Control Act (TSCA) in 1976, and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as the Superfund bill, in 1980. When CERCLA was passed, few were aware of the extent of the problem potentially created by years of inappropriate or inadequate hazardous waste disposal practices. Since implementing CERCLA, the U. S.Environmental Protection Agency has identified more than 40,000 potentially contaminated â€Å"Superfundâ⠂¬  sites. The Gulf War In August 1990 Iraqi forces invaded Kuwait, starting the Gulf War in which an allegiance of 34 nations worldwide was involved. In January  1991  of the Gulf War, Iraqi forces committed two environmental disasters. The first was a major oil spill 16 kilometers off the shore of Kuwait by dumping oil from several tankers and opening the valves of an offshore terminal. The second was the setting fire to 650 oil wells in Kuwait.The apparent strategic goal of the action was to prevent a potential landing by US Marines. American air strikes on January 26 destroyed pipelines to prevent further spillage into the Gulf. This however seemed to make little difference. Approximately one million tons of crude oil was already lost to the environment, making this the largest oil spill of human history. In the spring of 1991, as many as 500 oil wells were still burning and the last oil well was not extinguished until a few months later, in November.The oil spills did cons iderable damage to life in the Persian Gulf (see picture). Several months after the spill, the poisoned waters killed 20. 000 seabirds and had caused severe damage to local marine flora and fauna. The fires in the oil wells caused immense amounts of soot and toxic fumes to enter the atmosphere. This had great effects on the health of the local population and biota for several years. The pollution also had a possible impact on local weather patterns.

If c orrect, monitoring their behavior could provide advance warning of earthquakes, tsunami etc. However, the evidence is controversial and is not widely accepted.There are unsubstantiated claims about the Lisbon quake that some animals escaped to higher ground, while many other animals in the same areas drowned. The phenomenon was also noted by media sources in  Sri Lanka  in the  2004 Indian Ocean earthquake. [21][22]  It is possible that certain animals (e. g. ,  elephants) may have heard the sounds of the tsunami as it approached the coast. The elephants' reaction was to move away from the approaching noise. By contrast, some humans went to the shore to investigate and many drowned as a result. It is not possible to prevent a tsunami.However, in some tsunami-prone countries some  earthquake engineering  measures have been taken to reduce the damage caused on shore. Japan  built many tsunami walls of up to 4. 5  metres (15 ft) to protect populated coastal areas. Oth er localities have built  floodgates  and channels to redirect the water from incoming tsunami. However, their effectiveness has been questioned, as tsunami often overtop the barriers. For instance, the  Okushiri, Hokkaido tsunami  which struck  Okushiri Island  of  Hokkaido  within two to five minutes of the  earthquake on July 12, 1993  created waves as much as 30  metres (100 ft) tall—as high as a 10-story building.The port town of Aonae was completely surrounded by a tsunami wall, but the waves washed right over the wall and destroyed all the wood-framed structures in the area. The wall may have succeeded in slowing down and moderating the height of the tsunami, but it did not prevent major destruction and loss of life. [23] Natural factors such as shoreline tree cover can mitigate tsunami effects. Some locations in the path of the 2004 Indian Ocean tsunami escaped almost unscathed because trees such as  coconut palms  and  mangroves  absorbe d the tsunami's energy.In one striking example, the village of  Naluvedapathy  in India's  Tamil Nadu  region suffered only minimal damage and few deaths because the wave broke against a forest of 80,244 trees planted along the shoreline in 2002 in a bid to enter the  Guinness Book of Records. [24]  Environmentalists have suggested tree planting along tsunami-prone seacoasts. Trees require years to grow to a useful size, but such plantations could offer a much cheaper and longer-lasting means of tsunami mitigation than artificial barriers. The Love Canal chemical waste dumpIn 1920 Hooker Chemical had turned an area in Niagara Falls into a municipal and chemical disposal site. In 1953 the site was filled and relatively modern methods were applied to cover it. A thick layer of impermeable red clay sealed the dump, preventing chemicals from leaking out of the landfill. A city near the dumpsite wanted to buy it for urban expansion. Despite the warnings of Hooker the city eve ntually bought the site for the meager amount of 1 dollar. Hooker could not sell for more, because they did not want to earn money off a project so clearly unwise.The city began to dig to develop a sewer, damaging the red clay cap that covered the dumpsite below. Blocks of homes and a school were built and the neighborhood was named Love Canal. Love Canal seemed like a regular neighborhood. The only thing that distinguished this neighborhood from other was the strange odors that often hung in the air and an unusual seepage noticed by inhabitants in their basements and yards. Children in the neighborhood often fell ill. Love Canal families regularly experienced miscarriages and birth defects.Lois Gibbs, an activist, noticed the high occurrence of illness and birth defects in the area and started documenting it. In 1978 newspapers revealed the existence of the chemical waste dump in the Love Canal area and Lois Gibbs started petitioning for closing the school. In August 1978, the clai m succeeded and the NYS Health Department ordered closing of the school when a child suffered from chemical poisoning. When Love Canal was researched over 130 pounds of the highly toxic carcinogenic TCDD, a form of dioxin, was discovered. The total of 20. 00 tons of waste present in the landfill appeared to contain more than 248 different species of chemicals. The waste mainly consisted of pesticide residues and chemical weapons research refuse. The chemicals had entered homes, sewers, yards and creeks and Gibbs decided it was time for the more than 900 families to be moved away from the location. Eventually President Carter provided funds to move all the families to a safer area. Hooker’s parent company was sued and settled for 20 million dollars. Despite protests by Gibbs’s organization some of the houses in Love Canal went up for sale some 20 years later.The majority of the houses are on the market now and the neighborhood may become inhabited again after 20 years o f abandonment. The houses in Love Canal are hard to sell, despite a renaming of the neighborhood. It suffered such a bad reputation after the incident that banks refused mortgages on the houses. None of the chemicals have been removed from the dumpsite. It has been resealed and the surrounding area was cleaned and declared safe. Hooker’s mother company paid an additional 230 million dollars to finance this cleanup. They are now responsible for the management of the dumpsite.Today, the Love Canal dumpsite is known as one of the major environmental disasters of the century. **** Love Canal is an abandoned canal in Niagara County, New York, where a huge amount of toxic waste was buried. The waste was composed of at least 300 different chemicals, totaling an estimated 20,000 metric tons. The existence of the waste was discovered in the 1970s when families living in homes subsequently built next to the site found chemical wastes seeping up through the ground into their basements, forcing them to eventually abandon their homes.Love Canal was used from the 1940s through the 1950s by the Hooker Chemical Company and the city of Niagara Falls, among others, to dispose of their hazardous and municipal wastes and other refuse. The canal was surrounded by clay and was thought at the time to be a safe place for disposal—and, in fact, burying chemicals in the canal was probably safer than many other methods and sites used for chemical disposal at the time. In 1953, the Niagara Falls Board of Education bought the land-fill for $1 and constructed an elementary school with playing fields on the site.Roads and sewer lines were added and, in the early 1970s, single-family homes were built adjacent to the site. Following a couple of heavy rains in the mid-1970s, the canal flooded and chemicals were observed on the surface of the site and in the basements of houses abutting the site. Newspaper coverage, investigations by the State of New York and by the U. S. Environm ental Protection Agency, combined with pressure from the district's U. S. congressional representative and outrage on the part of local residents, led to the declaration of a health emergency involving â€Å"great and imminent peril to the health of the general public. Ultimately, in August, 1978, a decision was made by Governor Hugh Carey, supported by the White House, to evacuate the residents and purchase 240 homes surrounding the site. Shortly thereafter, the residents of nearby homes that did not immediately abut the site also became concerned about their health and conducted a health survey that purported to show an increase in the occurrence of various diseases and problems such as birth defects and miscarriages, which were attributed to chemical exposures.A great controversy ensued over whether the observations were real or reflected normal rates of such problems, and whether chemical exposures had, in fact, occurred. Eventually, political pressure resulted in families bein g given an opportunity to leave and have their homes purchased by the State. About 70 homes remained occupied in 1989 by families who chose not to move. The controversy at Love Canal followed on the heels of the heightened awareness that occurred in the 1960s about environmental contamination, and it contributed to public and regulatory concern about hazardous wastes, waste disposal, and disclosure of such practices.Such concerns led Congress to pass the Resource Conservation and Recovery Act (RCRA) and the Toxic Substances Control Act (TSCA) in 1976, and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as the Superfund bill, in 1980. When CERCLA was passed, few were aware of the extent of the problem potentially created by years of inappropriate or inadequate hazardous waste disposal practices. Since implementing CERCLA, the U. S.Environmental Protection Agency has identified more than 40,000 potentially contaminated â€Å"Superfundâ⠂¬  sites. The Gulf War In August 1990 Iraqi forces invaded Kuwait, starting the Gulf War in which an allegiance of 34 nations worldwide was involved. In January  1991  of the Gulf War, Iraqi forces committed two environmental disasters. The first was a major oil spill 16 kilometers off the shore of Kuwait by dumping oil from several tankers and opening the valves of an offshore terminal. The second was the setting fire to 650 oil wells in Kuwait.The apparent strategic goal of the action was to prevent a potential landing by US Marines. American air strikes on January 26 destroyed pipelines to prevent further spillage into the Gulf. This however seemed to make little difference. Approximately one million tons of crude oil was already lost to the environment, making this the largest oil spill of human history. In the spring of 1991, as many as 500 oil wells were still burning and the last oil well was not extinguished until a few months later, in November.The oil spills did cons iderable damage to life in the Persian Gulf (see picture). Several months after the spill, the poisoned waters killed 20. 000 seabirds and had caused severe damage to local marine flora and fauna. The fires in the oil wells caused immense amounts of soot and toxic fumes to enter the atmosphere. This had great effects on the health of the local population and biota for several years. The pollution also had a possible impact on local weather patterns.

Duffys poetry Essay

A critic has writ7ten that â€Å"Duffy’s poetry is primarily concerned with human failings†. To what extent do you feel this is true of ‘The Worlds Wife’? Refer to two or three poems in detail or range more widely through the whole collection. Carol Ann Duffy’s collection of ‘The Worlds Wife’ revolves a lot around the subject of human failings. Duffy’s use of everyday language allows her poems to be interpreted by everyone. In the collection of ‘The Worlds Wife’ she tackles serious issues such as gender, contemporary culture, alienation and social inequality. These themes allow her to writing to appeal to a contemporary audience and delivers key messages. The theme of arrogance is seen in several poems, in Mrs Icarus we see that she finds his arrogance unappealing and that she feels as if men feel they can defy the acts of God â€Å"he’s a total, utter absolute, Grade A pillock. † This is similar to Faust, who sold his sole to the devil in return for twenty-four years of unlimited pleasure, knowledge and power; he boasts â€Å"I spent the night being pleasured by a virtual Helen of Troy. † Dr Faustus’ lack of self control, ignorance and plain arrogance could be assumed to be a failing, although he lived a happy life his inhibitions to be successful he needed the aid of the devil therefore he was doomed from the beginning. Here we can see the obvious links between the two poems and how the two characters egotistical ways led to their failure. One interesting failure Duffy uses is seen in the poem ‘The Devils Wife’, Duffy interestingly splits this poem into six sections which all relate back to different themes, we see the value of a relationships, motherhood and repentance. The poem is written based on the background history of the Moors Murders, with the protagonist Myra Hindley and how she became besotted with sociopath Ian Brady. In the first part of the poem we as the readers see how Duffy, displays Hindley as being the ordinary office worker with a crush â€Å"I scowled and poured and sneered. I gave as good as good as I got till he asked me out† we can see that she was the one who initiated the whole relationship. The story changes â€Å"He entered me. † From this moment she was now his, this could be another failing that men have more control than women and she was just his puppet â€Å"he made me bury a doll. † Duffy uses an interesting metaphor here, she say â€Å"doll† instead of a child as a doll is thought to be a child’s toy and just a possession which they eventually no longer require. It ends with â€Å"I felt like this: Tongue of stone. Two black slates for eyes. Thumped wound of a mouth. Nobody’s Mam. † We can see that she has become so obsessed with him, her life has changed forever. Also we are able to identify another theme of motherhood, people were unable to understand how Hindley was able to commit the most abhorrent, sadistic and unforgivable crimes against children as women are associated with protective mother love. We then see that in the third part of the poem, Duffy uses a sonnet in an untraditional form; instead of it being the ordinary love poem, the lack of punctuation shows Hindley’s state of mind and she’s finally repenting and blaming Brady for all of the murders. The final part of the poem gives different forms of execution and she finally admits she was in fact the Devil’ wife. Although this poem is lengthy, the key themes all relate to the main subject of â€Å"human failings†, love is a key importance in this poem â€Å"He held my heart in his fist and squeezed it dry. † Here we can see that men are dominant in relationships and Brady was in control of Hindley, which could be deemed a failing. Also motherhood is a joyous gift in life and could be one of the most important things in life but Hindley displays apathy towards children and lets Brady control her life â€Å"I flew in my chains†¦where we’d buried the doll. † Finally we see another theme of repentance â€Å"Get me a Bible honestly promise you swear† but by the time she finally realised her mistakes it was too late. Another them used is Power, this could also be assumed as a failing. In Mrs Midas, in which she finds that everything her husband touches turns to gold; soon after she realises the marriage will not work because of her husband’s selfishness. â€Å"I thought of the Field of the Cloth of Gold and of Miss Macready. † Here we can see that her husband valued wealth above everything else, but it wasn’t until he accidently touched his daughter he realised the mistake of his greed that was his failing. In The Kray Sisters, Duffy subverts the original story by using female portrayals instead of men; the poem uses cockney slang which allows us as readers to interact more with the poem and makes it more believable. The Kray Twins ran a protective racket, and were well known ‘West End gangsters’. The poem actually displays the success of the twins and how they were feared among the streets. However interestingly this so-called respect may have given the Kray’s the authority they wanted â€Å"We wanted respect for the way we entered a bar, or handled a car, or shrivelled a hard-on with simply a menacing look† However ultimately this respect led to the demise of the twins and they may have ruled the west end during their time but landed themselves a life-sentence in prison. Was it really worth it? Respect and honour are meant to be earned with dignity not by threatening and violating people; therefore I think that although this poem contains positive connotations it ultimately displays a failing. Duffy’s collection of the Worlds Wife is an interesting selection of poems and it is clear that one of the major themes associated with the collection is Human Failings, although these are not seen clearly and not every persona fails the actions they carry out could be assumed as a failing. The ironical and satirical way Duffy writes displays the dark humour of The Worlds Wife we can see that Duffy tries to impersonate the wives of famous characters both factious and fictions.

Report Writing: Style and Structure

Report Writing: Style and Structure Summary Writing a report can seem daunting at first, but with a solid understanding of the fundamental structure and style used in constructing clear and concise reports, it can be achieved. The standard report format is as follows: Title, Summary, Introduction, Body, Conclusions, Recommendations, Appendix, References and Table of Contents. We will first look at how to prepare a report before the writing begins. Learning objectives At the end of the session, students will be able to: †¢ Write with a specific purpose and audience in mind †¢ Structure sentences, paragraphs and reports Write clearly and concisely Purpose and audience Before writing a report you should first identify some key factors, which will help you plan your approach and write with clarity. The first question you should ask yourself is, â€Å"what is the purpose of the report? † Purpose â€Å"What is it about, and what is it for? † It is beneficial to esta blish the purpose of your report before you start writing, so that you can think clearly on the subject, and produce a report styled to fit the needs of your purpose. Recognize what your report is for, (informing, instructing, guiding) and focus your writing on explaining the details.If for example, you want to write an instructional report for a team of colleagues, you know that you must focus your writing on providing clear concise instructions, which will allow your reader to comprehend the processes that you are describing. Audience â€Å"Who are you writing for? † The second question you should ask yourself is, â€Å"who is going to read this report and why? † Knowing your audience will help you determine how long your report should be, how it should be presented, and what level of terminology you should use to best attract and maintain the interest of your reader.If for example, you are writing a report to inform policy makers, you would want to focus on presenti ng your evidence clearly and concisely. We will now try an exercise on identifying audience and purpose: Exercise one Malaria Prevention You are a Health worker at the Ministry Of Health and have been asked to write a report on Malaria. You have access to the figures on Malaria incidents in the Country over the last five years, as well as access to the latest info on drugs and other barriers to prevent Malaria. 1. Describe the purpose of your report, and identify your audience.The sentence Now that we know how to identify our audience and define a purpose, we will look at how to write clearly and succinctly. Understanding how to structure a sentence is essential to conveying meaning clearly. Following are a few rules of thumb to help avoid ambiguous sentences: †¢ Keep it short and to the point. Many people have trouble with run-on sentences, creating ambiguity by attaching many ideas together with large combinations of commas, semicolons and dashes. Complete one thought and clo se out your sentence with end punctuation. †¢ Words for words sake.Avoid extraneous words, and parentheses that do not add to your point. †¢ Don’t leave it hanging. Sentence fragments can be just as confusing as run-on sentences. Make sure that you have completed your sentence and that it makes sense, before closing it out. For a comprehensive explanation of the inner workings of sentences and grammar, you can visit the links below. Sentence help: http://www2. actden. com/writ_den/tips/sentence/index. htm Grammar help: http://www. speakspeak. com/html/d10_english_grammar. htm We will now look over some common errors that can convolute sentences and obscure meaning.Sentence Fragment â€Å"Mark has finished his work on time. Since he started planning ahead. † The second sentence is a fragment here, because it does not contain enough information to complete a thought. Most sentence fragments are phrases that belong to the previous thought. To correct the problem in this instance, we simply remove the period. Correct â€Å"Mark has finished his work on time since he started planning ahead. † Run-on sentence â€Å"Jane loves Tom he is a good friend. † A run-on sentence occurs when you have two complete sentences that are not separated by correct punctuation.In this case we can correct it with a comma and a linking word, or by using a period. Correct â€Å"Jane loves Tom, because he is a good friend. † â€Å"Jane loves Tom. He is a good friend. † Exercise 2 Correct the following sentence fragments and run-on sentences. We will play Cricket tomorrow. If it doesn’t rain. In our survey we contacted 212 members of government 110 members of government responded. In order to obtain funding. You have to write clear concise reports. Michael loves to write reports he is talented at it and his wife’s name is Shelly. Structuring Sentences, Paragraphs and Reports Tell them what you’re going to tell them, t ell them, and then tell them what you told them. † The diagram below is an excellent example on how to write clearly and logically. We will now look at each part of this â€Å"map† and then see how the pieces come together. [pic] Introduction Introductory paragraph The introduction should explain the general ideas to come, as well as your thesis statement, which tells the reader what to expect from the rest of the report. The rest of the report should gather evidence and organize a case around your thesis statement. Topic sentencesA topic sentence is like a mini introduction to the body of your paragraph. Your topic sentence should explain what the body of the paragraph will cover, (just like your introduction explains what to expect in the report). It is a good idea to â€Å"map† out your report, by first writing topic sentences for each of the different paragraphs or sections of your report. 2. Body Support sentences Support sentences are the body of paragraphs . This is the section of your report that serves to provide evidence and examples that reinforce your thesis statement. Support sentences are also used to clearly explain and underpin main ideas. . Conclusion Concluding sentences The concluding sentence is used to reiterate the main points developed by the support sentences, and signal the end of a paragraph. They are also useful for adding emphasis to certain key points, through repetition. We will now look at how to create the different parts of a report outside of the general writing, which are: Title, Summary, Recommendations, Appendix, References, and Table of Contents. Title The title is your first contact with the reader, and should inform them succinctly about what they are about to read. SummaryThe purpose of a summary is to provide an overview of the report. It is not necessary to give detailed information in the summary, but rather to provide an indication of the type of information that the report contains. Average summa ries are between 100-150 words, and are generally written after the report has been completed, so that you know exactly what you are summarizing. Recommendations Recommendations are not an essential part of a report; however, if you are including one, it should follow from your conclusion. A brief statement clearly declaring your recommendations will suffice.Appendix An appendix contains materials that are peripheral, but relevant to your report. For example you may wish to include a glossary of terms in your appendix if you are writing a technical report for those who are not experts on the subject. You may also include copies of research tools such as questionnaires and manuals, as well as tables and diagrams that you feel would disrupt the flow of your report by breaking it up. If your appendix does contain tables, diagrams etc. , make sure to label them properly, so that the can easily be found when referenced.References If you have consulted or quoted any media sources, (print or otherwise) to help you compile your report, they must be acknowledged here, as well as in the text. Citing your resources not only avoids running into plagiarism issues, but strengthens your work by backing up your report with evidence from the work of others. If you are quoting directly from someone else, the quote must be followed by the author’s surname and date of publication in round brackets, e. g. Calvino (1983). A standard bibliography is an alphabetized list ordered by Author’s surnames.For a book you must include: the author’s surname and full name, or initials; the full title of the book; the edition (if other than the first); the place of publication; the publisher, and the date of publication, e. g. Calvino, Italo. Palomar. Torino: S. P. A. , 1983. For a complete guide to correct citation, visit: http://www. liu. edu/cwis/CWP/library/workshop/citmla. htm Table of Contents A table of contents is a page containing numbers that correspond to differe nt parts of your report, allowing readers to jump between sections quickly.Number and title the different portions of your report, (such as â€Å"1. 2 Medical advancements in treating Malaria† â€Å"1. 3 Government funding for treating Malaria† â€Å"2. 1 References† etc. ) and then create a corresponding list of contents that lists the page number as well as the reference number, which should be sequential, starting from the summary. A good starting point for mapping out your table of contents is to do it corresponding to your topic sentences. Below is an example of a â€Å"mapped† checklist that puts all of the steps we have learned together followed by a table of contents.It is a good guidance tool to use when preparing to write a report. The â€Å"mapped† checklist is modeled on the Malaria prevention exercise we completed earlier. â€Å"Mapped† Checklist for Malaria Prevention 1. Who is it for? Health workers in district offices. 2. Wha t is it about? Malaria prevention – success stories over the last five years. 3. Title Let’s Win the Battle Against Malaria 4.

Native american and the fur trade Essay Example | Topics and Well Written Essays - 500 words

Native american and the fur trade - Essay Example It changed their way of life - the way they moved about, the way they hunted, the way war became easier due to their increased mobility, but more importantly the introduction of the horse gave Native Americans a new understanding to breed, raise, and train horses for trade to the "white man". This was something they could control. Colonial American was eager for more land and began to push westward. The flood of settlers pushing west was led first by "mountain men" - explores who first journeyed west and made contact with the plains Indians. The United States government had begun forcing tribes from the eastern portions of the United States to relocate west of the Mississippi River and later on reservations - designated land given to individual tribes. One of the things Native Americans soon discovered was that the Europeans loved fur and initially these "mountain men", but later entire fur trading companies were willing to trade guns and alcohol for pelts. Disease introduced to Native Americans had devastated the Indian population. Although diseases such as small pox killed thousands of Native Americans, the introduction of guns and alcohol had a longer lasting, damning effect on the Native American way of life. Changes from past altered their life forever.

Will a global society and economy still need a dominant, Essay

Will a global society and economy still need a dominant, professionally-run global press Describe what it would look like or what would replace it. Consider what its role and influence would be - Essay Example Due to technological revolution, there has been a fast development of the digital communication through the global press (Flew, 2007). For capitalists, they argue that the human races is entering the golden age where all that people would need to do is to sit back and let the markets and technology do the shopping for them. This is because the global press industry is changing quite fast and hence a demand for instant coverage and the need to decrease the budgets with the sole objective of releasing ethical news. With all eyes on globalization, change in technology and ethical transmission of news with emphasis on deadline ethics, professionally run global media will change how individuals think with the contemporary society (Flew, 2007). Whereas previously the media system were primarily remote, in the past few years we have witnessed the growth of the professionally run global press with two distinct but related facets. This is because professionally run global press is cutting across the world by facilitating faster cross cutting of the world through technology. This is to aid the firms in the global economy to capitalize on the potential of growth abroad without being impacted by flurry competitors given that the local economies already is saturated with incremental expansion. The other facet is that the consolidations and convergence all depend about the day given that some of the global media houses are increasingly becoming concentrated. This is because the major players in the media industry are majorly branches of the global media conglomerates due to the onset of mergers and acquisitions (SHERMAN, (2002, October 2). It is a fact that the global American media leaves many gaps to be desired whether you want news about the media, the war on terrorism, global trade or simply general information and the understanding of the majority of the world’s population who are non-Americans. This has made the reporting of news difficult due to the

Proposal finance - Essay Example e main objectives are, first, determine the cause the global financial crisis and secondly, the effect of the financial crisis on the developing country. The research will attempt to answer the following questions; what caused the financial crisis and what was its impact on the least developed nations. The results of the research will be of great importance to both governments and private sector in both developing and developed nations alike. It will enable the governments to come up with strategies for predicting and preventing future occurrences. The private sector will be able to cushion their businesses from a financial crisis and learn how business practices can cause a financial crisis. Many economists consider the 2008 to 2012 financial crisis as the worst since the great depression of the 1930’s. It led to the collapse of financial institutions, decline in consumer wealth (Muma, 2012, p. 6); the stock market dropped worldwide and mortgages default in the housing sector. What started as US mortgage crunch (Sun et al., 2011, p. 2), extended to the other nation especially the European Union. On September 14, 2008, the fate of Lehman Brothers was to be decided (Dolezalek, 2011, p. 7). The eventual fall of Lehman Brothers undermined the confidence and trust of the investors in the financial market. One year earlier, the Bank of England has bailed out Northern Rock, a large mortgage lender (Dolezalek, 2011, p. 7). The financial and banking crisis that started in the developed nation reached the least developed nation through at least three channels. First, the crisis led to sharp decline in world trade volume (Alabi et al., 2011, p. 3) and commodity prices (Alabi et al., 2011, p. 116). Secondly, the foreign direct investment started declining since 2007 and hurt most, the mineral and oil exporting nations (Nafziger, 2012, p. 546). Thirdly, it led to a reduction in the foreign remittances to the least develop countries. The research will extend the body of

Galen Strawson Considers Freedom of Will to Be Profanation Essay

Galen Strawson Considers Freedom of Will to Be Profanation - Essay Example I disagree with Strawson’s position and posit that humans can and should be held responsible for their actions because, as Strawson points out, even if the situation is such that you have a gun to your head, you still have a choice.   The unpleasantness of the choice does not nullify the presence of the choice or the fact that we always have the option to choose either the pleasant or more tolerable route over the unpleasant option and vice versa.According to Strawson’s analysis, humans lack the capacity to make free choices.   The influences of society, parents, friends, teachers, and all of the contributory factors that shape each of us into the unique individuals we are countermand our ability to freely make decisions.   Since we do not control who we are and who we determine the decisions we make, logic dictates that we are not engaging in free will because we did not have the power to shape who we are.   Additionally, Strawson states that, even if a person changes who they are, this does not mean they have free will because heredity and experience have already affected you in ways that you can never change.   The way a person is ultimately has a significant effect on how they are able to change and what attributes they are able to change, which causes the redundancy in the whole concept of change to facilitate free will.  Strawson begins by presenting the gamut of views concerning free will from the perspective of the Compatibilists and the Libertarian and No-Freedom Incompatibilists.   The philosophical view of the Compatibilist is that humans have free will and are morally responsible for their actions (Strawson, 1995).   According to Strawson, Compatibilists base their analysis of the condition of free will on the fact that it is compatible with the concept of determinism, which states that each action creates a pattern that makes subsequent actions or reactions unavoidable.This theory deems the determining factors that aff ect personality irrelevant and maintain that free will is absolute, despite the inclusion of determinism.   However, the presence of determinism in the Compatibilist view of free will actually nullify the viewpoint because how can you freely choose an option that has been predetermined?  

The Use of Force by Police, Specific Cases and their Implications Research Paper

The Use of Force by Police, Specific Cases and their Implications - Research Paper Example Force is used by the police to overcome resistance to their authority and to protect both civilians and officers. It is necessary that they have this ability in order for them to carry out their function, and the use of reasonable force is legal. However, the subject is one of significant contention, in regards to both non-deadly and deadly force. The use of force is often connected with racism, with significant concern by civilians that many instances where force is used are the result of racial profiling. There is rising debate about whether the police overstep their boundaries in the use of force, using force when it is not necessary, and in order to subdue or suppress civilians that are involved in undesirable, but not illegal actions. Examples of this include use of police force on civilians during peaceful protests, and using excessive force on particular races but not others. This had lead to concerns that control surrounding the use of force in the police is severely lacking. The manner in which police use force is varied and depends on the circumstance, the individuals involved and the agency in which the officer is from. The most basic form of force involves the use of handcuffs. Other non-lethal forms of force include the use of conductive energy devices (CEDs) such as tasers, and of aerosol sprays such as Oleoresin Capsicum (OC) spray, also known as pepper spray (MacDonald et al., 2009). . Firearms are also used, although the rate at which they are discharged is low, with one study estimating at in 0.6% of incidents a firearm was discharged . There are no national laws or regulations that control the use of firearms within the police, and as a consequence, policies differ between cities and states. The rules and directives concerning the use of force differ between agencies. Within the United States, 45% of local and state law enforcement agencies have been found to allow the use of OC spray, and 20-30% allow the use of CEDs to bypass passive resistan ce . Likewise, different agencies and states have different follow-up procedures for the use of force. The amount of force used by police has been found to differ significantly depending on the authority of the police officer. Detectives were found to be considerably more forceful than patrol officers under the same types of situations . Concern for the use of force by the police is partially connected to the lack of discipline for police officers that use force that is greater than the situation requires, even when the force that was used was clearly unjustified. In the case of the use of lethal force through firearms, following incidents it is often unclear whether the force used was unjustified or justified. As the cases are reviewed by the police, there are few cases where the use of force is considered unjustified and as a consequence there are few criminal charges laid . The definition of justified force that is used by the police in these investigations does not always match this

Commercial Dog-Breeding Facilities Essay Example for Free

Commercial Dog-Breeding Facilities Essay Pet shops give many people the impression of happy, eager, and healthy puppies that are in desperate need of a home and family. Sometimes people feel bad for the animals stuck in the small cages and decide they’re going to save or rescue them. People who buy these animals don’t realize that they’re supporting the commercial dog-breeding industry. Commercial dog-breeding facilities treat animals as a product; they are concerned with quantity and the profit they’ll receive instead of quality and the animals’ health. These facilities need to be banned for three reasons: to prevent further health deterioration of the animals; to preserve the lowering of breeds’ genetic traits which result from unregulated breeding; and they give reputable breeders a bad name. Before we examine specific issues surrounding professional dog breeders, first we should define some terms and give a general background of the problem. Many people have heard about the animal cruelty behind puppy mills; however, they have no idea about commercial dog-breeding facilities. The term â€Å"puppy mill† is used to describe large-scale dog breeding operations that place income over the animals’ welfare. Puppy mills don’t breed responsibly and the conditions they keep the animals in are generally illegal. Commercial dog-breeding facilities are also large scale breeding facilities that place the well being of animals below making a profit, yet these facilities are subject to United States Department of Agriculture (USDA) regulating and enforcing of the Animal Welfare Act (AWA) laws and regulations. The USDA regulates the breeding facilities with the minimum standards for the animals’ health; these are the same laws that are used for chickens, cows, pigs and other animals, which are slaughtered. The law requires that each animal is provided with â€Å"adequate housing, handling, sanitation, nutrition, water, veterinary care, and protection from extreme weather and temperatures† (USDA Animal Welfare Act). The USDA does not have the funds or proper training to enforce these laws, so most commercial dog-breeding facilities continue to thrive while their animals are suffering. The USDA also does not have any regulations for the facilities if they sell directly to the public, which includes online sales. These loopholes in the system cause for an unbalanced, irresponsible, and unhealthy system of dog breeding. Having seen that commercial breeding in general is a problem, let’s examine the first specific issue, that of the deterioration of dogs’ health at these facilities. Commercial dog-breeding facilities don’t keep the dogs’ health in mind, even in severe and life threatening cases. When it comes to animals’ health in these facilities, there are government rules and regulations with punishments for violators and repeat offenders. Inspectors must visit commercial dog-breeding facilities at least twice a month; if there’s a violation, they file reports and give out punishments to those who have violated the laws. A May 2010 audit report filed by the United States Department of Agriculture uncovers the truth of inspectors’ visits to commercial dog-breeding facilities: â€Å"Expecting that the dealers would improve their standards of care, the agency chose to take little or no enforcement actions against most violators† (USDA Animal and Plant Health 10). Inspectors wouldn’t choose to give any stipulation to violators, even when they were repeat offenders. Inspectors never followed up visits to ensure that the proper changes were made, nor did they make the proper amount of check ups required per year. The conditions of commercial dog-breeding facilities are disgusting and irresponsible, and the dogs are not properly brought up and cared for. The May 2010 audit report filed against USDA inspectors mentions an Oklahoma breeding facility that had numerous dogs infested with ticks; pages 11 and 12 feature shocking photos of the dogs taken by the inspector. The breeder had no records of any medical treatment ever given to any dogs, and if a re-inspection were to be given then there would be no way of knowing if the animals were really treated or euthanized. The inspector cited the breeder for an indirect violation, despite excessive ticks being a direct violation in the Dealer Inspections Guide. He told the breeder to take only eight of the infested dogs to the veterinarian. The inspector didn’t require any documentation of the treatment nor did he indentify which dogs needed treatment, so there is no way to know what happened to the dogs in the pictures mentioned above (USDA Animal and Plant Health 11-12) The dogs kept for use as breeding stock live their entire lives in the small cages, being bred too early, too frequently, and for too long. These dogs generally have the most severe health and behavioral problems. Franklin McMillan, DVM, is well known for his studies on animals affected by trauma; one of his studies compared dogs that were used as breeding stock in commercial dog-breeding facilities to dogs owned by the general public. The dogs were put through the Canine Behavioral Assessment and Research Questionnaire (C-BARQ), which rate many psychological behaviors and their intensity. The C-BARQ is given an average of two years after the breeding stock dogs have been in their adoptive homes, with 76 different breeds and both sexes included. The breeding stock dogs were compared to a sampling of the dogs owned by the general public by matching their breed, sex, age, and neuter status. This test was conducted to see if the breeding stock dogs do actually consistently â€Å"display persistent behavioural and psychological abnormalities† (McMillan, Duffy, and Serpell). The results confirmed that the former breeding stock dogs did indeed have considerably higher behavior problems. It’s often argued that dogs used in commercial dog-breeding establishments have psychological issues and this has now been confirmed by this study. The dogs that are used as breeding stock are forced to spend their lives solely for production of profit, and when they no longer can produce they are usually euthanized. Commercial dog-breeding facilities do not provide the dogs they keep with adequate care; they leave the facilities unkempt and dirty, and don’t allow the animals exercise. The dogs not only have physical side effects but also psychological ones after being in crowded cages isolated from human contact. The inspections that are supposed to make sure the facilities are keeping up with the USDA regulations provide no help for the situation. It’s a rare case to have inspectors following the Dealer Inspections Guide with follow-ups, citing when necessary, and issuing violations. The inspectors have many weaknesses; there was no enforcement against violators, the inspectors didn’t follow procedure, they rarely provided any documentation or evidence, and they delayed telling breeders to send suffering animals for treatment (USDA Animal and Plant Health). Commercial dog-breeding facilities don’t keep the breeding stock dogs or puppies in sanitary conditions or keep them healthy; this is a direct violation of USDA regulations. Now let’s examine the second major issue surrounding dog breeders, which is that they lower the standards of the breeds. The American Kennel Club (AKC) is the largest purebred dog registry in the United States; people may pay up to thousands of dollars for purebred dogs that are AKC registered. The issue is that these AKC papers’ value is not what it seems; they do not guarantee that the dog is purebred, healthy, or within proper breed standards. Leslie LeFave, writer and dog enthusiast, states how breeders obtain AKC papers for their litters: Breeders send to AKC for a litter application. They then fill out this form with who the mother and father of the puppies are, with their AKC registration numbers, date of birth, and certificate number[†¦]The breeder then sends this paper work (litter registration) to AKC to add these puppies to their database and the breeder gets AKC papers and numbers for each puppy. No questions asked. (LeFave) The AKC papers only guarantee that an application was filled out and payment was received; the AKC does not check the breeders’ claims, including the breed, health, and number of puppies born. The AKC continues to hand out registration papers as the checks come in and more puppies are sold with AKC registered papers that don’t necessarily belong with them. Many people choose purebred dogs because of a specific look, and certain traits they desire in their companion. Commercial dog-breeding facilities’ only goal is to make money, so they will breed any dogs that match the certain looks typical of the breed without taking care to prevent diseases and inbreeding. This way of breeding only multiplies the chances of serious genetic disorders in each puppy and leaves the personality traits not even considered. LeFave explains how a responsible breeder chooses which dogs to breed: â€Å"Having quality dogs requires a breeder to invest money and time in their dogs. A good breeder does genetic health testing if available for their breed, and spends hours going over pedigrees and learning all they can about their breed.† No commercial dog-breeding facility cares about the long-term health of the animal; they will not check for serious diseases in the dogs used for breeding stock or in the puppies they’re selling. Commercial dog-breeding facilities are not responsible breeders; they produce unhealthy animals and deteriorate the breeds’ genetics and standards. Purebred dogs are more susceptible to genetic disorders because the large breeding facilities don’t take care to make sure the breeding gene pool is large, diverse, and free of the disorders common to which breed they’re breeding; therefore, many disorders carried, even those that are recessive, are amplified. Carrie Allan, a writer for All Animals magazine, has found in many studies that 30 to 70 percent of Cavalier King Charles Spaniels (a small toy breed) will end up with Syringomyelia, a serious life threatening disorder. Syringomyelia is a disease in the spinal cord in which cavities fill with fluid near the brain; sometimes even the dog’s brain will swell past the skull. This is not uncommon for a purebred dog; they have many serious genetic diseases that the buyer is unaware of until their dog starts suffering. Commercial dog-breeding facilities do not screen for the common diseases or breed to prevent them. They are irresponsible, reckless, and create long-term problems with breed standards and traits. The third major issue with commercial dog breeding facilities is that their practices often bring disrepute onto reputable breeders. Responsible dog-breeders do exist, and they produce healthy and happy puppies that are true to their breeds’ standards. These breeders also know of the horrible situations commercial dog-breeding facilities keep their animals in, and they are also in the fight against them; they cause responsible breeders to lose more money, give them a bad name, and deteriorate the breeds of dogs they love. The law requires breeders to have kennel or vendor’s licenses, but many states and counties cut commercial breeding facilities breaks, not requiring them to have these licenses. The small responsible breeders, who only produce about twelve puppies a year, do not get any break, they must have licenses, and they must pay their taxes on the dogs. For example, in Ohio a report was given by Michael W. McKinney, the Public Information Officer for the Ohio Department of Taxation, on these vendors: â€Å"None of the 410 known dog breeding kennels in Holmes County with 11,033 dogs, including 41 with more than 50 breeding dogs each, have a vendor’s licenses.† (Allen). The state is not helping any small backyard breeder, but the large commercial ones, who should be required to have a license so that their dogs can be tracked and give an idea of their profits. When responsible breeders breed two dogs, they put a lot of effort into which animals they choose; they look at thei r family trees, they raise them in a suitable environment, and they make sure the animals are going to a home that’s a good fit. Purebred dogs have a significantly higher chance of carrying diseases, which is why good breeders make sure that the common diseases in the dog breed that they’re producing doesn’t end up in their litter. They have tests done to be sure the diseases aren’t present in the dogs they’ll breed; they make sure that the animals are healthy, then breed them, and also check each puppy before they sell them to ensure they’re healthy. For example, golden retrievers have a significantly high chance of developing hip dysplasia, a disease which causes improper developing of the hip joints, and a good breeder will prevent this as best as they can. Not only do puppies from reputable breeders have lower chances of carrying diseases, but also they are mentally healthier as well. When a dog is brought up in a family environment with daily exercise and its mother to raise it, it has a solid foundation to grow on. A dog that hasn’t been properly socialized can create many problems for an owner, which can include being aggressive to people and other animals. If the puppy were properly socialized then other people and animals would only be something the puppy has seen before and can coexist with. These breeders take a lot of time to make sure the puppies are brought up properly and don’t want to be associated with commercial dog-breeding facilities, which don’t provide the proper amount of care to their puppies. The reckless commercial dog-breeders give the wrong impression about the industry as a whole, and they cause high taxes for reputable breeders who aren’t doing it for profit but who want to see the breed they love thrive. Responsible breeders want their dog breed to be healthy as a whole; they don’t like having to see many beautiful, perfect dogs go to waste because of careless breeding, which produces a higher chance of disease in the breed. Large facilities make dog breeding seem like a product, while small, responsible breeders take great care to raise these animals for families. Commercial dog-breeding causes great stress and problems for responsible dog breeders, which are in it for the dogs, not a profit. We have seen that puppy mills and many large â€Å"government inspected† dog-breeding businesses produce ill dogs with degenerated breed traits and cast a negative light on the entire industry. Nevertheless, many people purchase puppies from these facilities because the canines are cheaper and the buyer feels he or she is â€Å"rescuing† the puppy, as if it were in a dog pound. Some people feel that commercial dog-breeding facilities may have negative sides to it but a responsibly bred purebred puppy is too expensive. Yes, many quality puppies can be up to thousands of dollars, and there is a reason for that. Responsible breeders don’t have a large-scale operation that shoots dogs out quick enough for a huge profit; they run their business out of their homes; they raise puppies with their family and put as much time and effort into breeding the right dogs as they do into raising them in the first weeks. The dogs from responsible breeders will not only have papers, but they’ll have papers that actually match up to them. These dogs will be healthy and of good genetic background, and that is what you’re paying for. If the problem is entirely money, then a shelter dog is the right choice; they are priced not for profit but for affordability and sustaining the shelters ability to stay afloat. From personal experience, I know that the local pound, Danville Boyle County Humane Society, a non-profit organization, provides animals at a very reasonable cost with many benefits for the owner. Not only is the buyer saving a life, but also all animals come spayed or neutered, de-wormed, with rabies vaccinations, and for dogs, they have the Bordatella vaccination (for kennel cough), and Distemper vaccination (for parvovirus). These vaccinations are for the most common diseases that leave animals at a very high risk of death. All of this is provided with your puppy for only $100, and for dogs and cats $75. Compared to the price of dogs from pet stores, online sellers and commercial breeders, that’s an unbeatable price, especially when they provide the animals already with proper health records. And many shelter animals are also purebred, not just mixes. A shelter is the perfect spot to go if you want an inexpensive and healthy animal. There is no reason for money to be the issue in acquiring an animal from a commercial dog breeding facility. If you don’t have enough, then a shelter or rescue organization is the perfect place, healthy and inexpensive. If you care about the background of the animal and want to show it, then dogs from a responsible breeder are much better suited for show; they will be able to provide you with a much better representation of the dog’s breed than a large scale breeding organization. You can see how those who believe that commercial dog-breeding facilities do not supply animals with the best living conditions, but provide them cheaper than reputable breeders are in the wrong. In the long run, dogs from large-scale facilities could end up with very expensive healthcare, having to buy a new dog, or even facing the heartbreak of being forced to euthanize it. Money is a big deal in our world right now, and buying a dog isn’t something that should add to that. Shelter dogs are cheaper, and dogs from good breeders are healthier, with much lower vet bills. In summary, commercial dog-breeding facilities are operations to produce maximum profit and leave the animals to fend for themselves; commercial breeders are leaving the important and necessary aspects of a good business behind. They are not making sure the animals involved are healthy and happy, they don’t mind when their â€Å"product’s† name is diminished, and they don’t care about other businesses, people, or animals harmed from their actions. Many of their dogs are euthanized, or have painful and serious diseases from their reckless breeding. Responsible breeders are getting a bad name from these facilities and shouldn’t be associated with them because they’re quite the opposite. And while buying a dog from a reputable breeder is more expensive than getting one from a puppy mill or online, the healthy dog will cause you much less in vet bills, and will be able to stick around till it’s old. Other options are shelter dogs, which are generally mixes and are much healthier dogs than purebreds, and rescue organizations, which can give you a cheap purebred with a much clearer background of where it came from. Commercial dog-breeding facilities don’t offer benefits to anybody involved in the industry; they provide unnecessary harm to many animals and people who don’t realize where their cute puppy actually came from. Not only are these facilities harming animals, but also our country as a whole, because they get tax breaks and are an unstable, unreliable industry that does shady work. These large-scale operations should be stopped and prohibited from business before more puppies are harmed, people are ripped off, and the country’s laws a re ignored.
