These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake. Human health is at great risk due to the untreated waste that is dumped in Lake Huron each year. The untreated sewage contains many viruses, two being Giardia (an intestinal parasite), cryptosporidium, which causes intestinal illnesses and even death. E. coli a more familiar virus has elevated its concentrations in Lake Huron, found in either animal or human feces, which causes diarrhea, nausea, and stomach cramps. ("Testing the waters,"
Scientists were studying this correlation and discovered some of the reasons for this higher mortality rate. Some otters are caught and killed in fishermen’s nets, some drown in lobster pots, and predators such as sharks kill some. A final explanation for their low population in California is infectious diseases, which mostly kills
2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
The plaintiffs alleged that ingestion of toxic chemicals (trichloroethylene and tetrachloroethylene) used in this industries, which were tested in water samples from municipal wells, were responsible for the severe health effects. According to those who drank it, the water smelled and had an objectionable taste. The case, which eventually grew to involve eight families and three defendants (UniFirst Corporation), raised considerable hopes. One resident, Ann Anderson whose three year old son was diagnostic with leukemia in 1967, started to believe that the water produced by H and G was responsible for the group of leukemia cases and other illness in her neighborhood. Jimmy Anderson, Anne’s youngest child, died of acute lymphocytic leukemia in 1981, at the age of 12.
The cases of Anderson et al v. Pacific Gas and Electric and Jones v. Scotchwood are very similar yet have significant differences. Four decades after one of the world’s largest utility started dumping 370 million gallons of cancer-causing chemicals into unlined ponds in Hinkley, California, their actions were uncovered. There negligence caused many people and domestic animals in the high desert town of Hinkley to get sick. In the town of Scotchwood, the water pipes running throughout the town were deteriorating causing the parasite “Pindia” to contaminate the water. This parasite was not an immediate threat to healthy people of Scotchwood but to the people already sick with diseases causing weakened immune systems.
The first couple of years were not easy for the settlers. The question is Why did so many colonist die? To start off with, one of the problems they faced was environmental problems. Many of Jamestown’s colonist died because of brackish water which was some salty water due to the mixture of fresh and salt water, because of the tides that would happen twice daily. Also, they would dump their human waste into the water and make it even more contaminated so when the people of Jamestown would drink or use the water it would make them ill and even to the point that they died.
Residents went to emergency shelters because of the radiation. Equipment failure, human error, and bad luck would conspire to create America’s worst nuclear accident. The impact of Three Mile Island was terrible, there was a massive cleanup. The cleanup started in August of 1979 and officially ended in December of 1993. The cleanup cost about 975 million dollars.
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
In this environmental disaster, 10 cubic meters of water and 4.5 million cubic meters of potentially toxic slurry were spilled into virtually untouched forest, lakes and rivers. If something like this happens at the Pebble Mine, then most of the fish and wildlife in Bristol Bay would be in danger of being killed. A species that would be greatly affected by this is the sockeye salmon. More than half of the world’s population of these fish lives in Bristol Bay. This means that the survival of this species would be threatened.
B. There are patches in the ocean that are thick, like plastic soup, that have actually been given names. The largest of these has been dubbed The Great Pacific Garbage Patch and it is about the size of Texas. We throw away about 2.5million plastic bottles an hour. C. if not stopped over time the earth with slowly decay and changes in the environment will take place such as acid rain or water that’s become to toxic to drink plus animals will die from the trap like waste.
