Red is the endangered areas In image 2, the most endangered reefs are in areas that are considered “Third World”, where populations have limited access to education. The people here are concerned mostly with putting food on the table now, later can wait for another day. There is a problem with reef systems today that directly comes from people who probably did not know that they were causing it. Runoff from sewers, especially untreated sewage kills corals by: * Suffocating corals and zooxantheallae by covering them with sludge and cutting off
The procedure consists of injecting a special fluid made up of chemicals and sand into the ground at high pressures to squeeze the natural gas back up through the rocks. By injecting this certain fluid we are leaving mercury, lead, hydrochloric acid, methane, and other poisonous chemicals left to rest in our earth’s crust. Studies show that more than 90% of fracking fluids are left underground. Because we are permanently polluting our land we are putting our environment at high risks of becoming destroyed and it is effecting human health. One resource that is at high risk of being contaminated due to fracking is water.
Companies have deposited their waste in the lake, which has caused the lake to be shut down because humans are getting sick and even dying from the polluted waters. Viruses, pathogens, chemicals and toxins are all part of this pollution, which affects recreation, jobs, and habitats of animals. Fishermen have not spent money fishing for sport due to the drastic reduction of the salmon population at Lake Huron. Recreational hours at the lake have also seen a drastic decrease. This devastation affects a majority of the U.S. being one of our largest sources of fresh water, and will only continue to deplete, as companies carelessly dump their waste into the lake.
One con is that there will be many jobs at the mine, but just not nearly as many jobs that Bristol Bay employs in the salmon industry. Another, and possibly the biggest, disadvantage of building the Pebble Mine is the negative effect on the environment in Bristol Bay. Although the company managing this says that there will be a bad affect on the environment, history tells us otherwise. We can look at the Mount Polley gold mine disaster. 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.
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.
Throughout the Civil War, medical knowledge was extremely basic. Many doctors didn’t understand infection, and those who did, did little or nothing to prevent it. Approximately two thirds of the soldiers died from infections as a result of unsound hygiene and sanitary conditions. Disease was extremely prominent in Civil War camps because of the disgusting conditions that the soldiers had to live in. Even though during the civil war, many medical advancements were being made, they were not being made quick enough to save approximately 400,000 soldiers who died from disease and infection.
(Document A) Since there was a short supply of fresh water, many colonists died of dehydration. Additionally, the document stated that waste in early Jamestown tended to cluster instead of flush away. These mishaps caused disease which eventually led to death. Another hardship the colonists had to endure was their exposure to new deadly diseases. Nearly 70 out of the 110 original colonists lost their lives by
Just over 50% of the population had been immunized against infectious diseases before the earthquake, well below the World Health Organization goal of 90%. According to figures from the Ministry of Public Health and Population, there are also approximately 4,000 amputees that need ongoing support, which is particularly devastating in a country where the majority of the population travels by foot or bicycle (Office of Haiti Special Coordinator, 2011). Cholera is an outbreak caused by the lack of clean water and washing facilities. Clean water and soap will dramatically slow the disease from spreading. There was a Cholera outbreak in Haiti due to the lack of these two basic necessities.
When we refine or even dig up oil sands we produce harmful chemicals. Since Alberta oil sands are located near major rivers some of those chemicals end up in the rivers. The most famous case is with the Athabasca River, where the water is contaminated by many harmful chemicals. The Athabasca water ecosystem is slowly being poisoned and so are the people that use the water for their water supply. The oil sands maybe a large part of our social and economic structure, but they are slowly ruining our environment.
Over Consumption vs. Under Consumption Throughout the world there have been numerous diseases that derive solely from food consumption. Various countries suffer from infection due to the lack of food, whereas other countries suffer from the over indulgence of food. In Haiti, the majority of food borne illnesses comes from the lack of consumption. According to John Eyles, Tuberculosis is the main infectious disease that is common in areas of poverty (Eyles).
