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.
When the EPA was created in 1970, it was headed by William Ruckelshaus (1932-), a loyal member of the Republican party who earned a reputation as a skilled administrator, who was able to work effectively with environmentalists as well as businesspeople.The EPA faced little criticism until the early 1980s.or example, for fiscal year 1991, at the end of the Bush administration, the EPA's budget was just over $6.09 million. President Clinton's proposed budget for fiscal year 1999 was over $7.77 million, a 6 percent rise as compared to 1998.
