Unknowingly factories burned fossil fuel causing what we call the greenhouse effect. Unfortunately, factories continue to burn these fuels.
also causes acid rain. Acid rain is caused by oxides of sulfur, carbon, and nitrogen from burning fossil fuels combine with moisture in the air. In 1981 alone, 264 million tons of waste was produced in the United States, 5.5 million tons of it was considered hazardous. Five years later the United States generated 1,770,000 cubic feet of solid and liquid radioactive waste.
has been known to cause ecological imbalances. DDT was used as an insecticide up until 1972. It almost wiped out the Bald Eagle population. It caused the birds to lay eggs so thin shelled eggs the eggs were unhatchable. Laws banned the use of DDT and also required the reduction of lead in gas. DDT is still used in developing countries on the malaria-carrying mosquito. Oil spills also have harmful effects, luckily chemicals can neutralize the oil before massive damage occurs. In 1983 the Dow Chemical Company's factory, a major producer of chemicals, showed contamination from dioxin. Dow undertook a 3 million dollar study of the material. The company announced that Dioxin is less health and life threatening.
High-temperatures are used to reduce the toxicity of waste. These processes use plasma technology to make the waste more environmentally friendly. Plasma treatment reach temperatures up to 1,650o F. In the United States incineration is a primary way to get rid of liquid waste. This process eliminates waste in two stages. One is partially burning the waste with insufficient air and then they ...
