During photosynthesis, a chemical called chlorophyll absorbs the light energy and encourages a reaction between carbon dioxide and water that results in glucose and oxygen. Oxygen is expelled as a waste product from the plant, and it enters the atmosphere.
The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the president and approved by Congress.
The rest of Nixonâs term was no less eventful, and it saw the Endangered Species Act passed in 1973 and the Safe Drinking Water Act in 1974. You may not like Nixon, I sure donât, but he presided over a time that saw more powerful environmental protection laws enacted than any before it.
