What is the role of the US Environmental Protection Agency?

The U.S. Environmental Protection Agency (EPA) is an independent agency of the federal government of the United States that was created in 1970 under President Richard Nixon to protect human health and the environment by writing and enforcing regulations based on laws passed by Congress. The EPA's mission is to ensure that Americans have clean air, land, and water, and that they are protected from exposure to hazardous substances that can cause serious health effects.

The EPA sets and enforces standards for air and water quality, regulates the use of pesticides and other chemicals, manages hazardous waste, and provides research and technical assistance to support environmental decision making. The agency also works with businesses, state and local governments, and other organizations to reduce the environmental impact of their activities and promote sustainable practices.

Overall, the EPA plays a crucial role in protecting public health and the environment in the United States, and its work has a significant impact on the lives of Americans every day.
