The U.S. Environmental Protection Agency (EPA) was established in 1970 by President Richard Nixon. The agency was created in response to growing public concern about the negative impacts of human activities on the environment, such as air and water pollution, and to consolidate and coordinate the various federal programs dealing with environmental protection. The EPA is responsible for implementing and enforcing federal laws and regulations designed to protect the environment and public health. Over the years, the agency has played a key role in addressing a wide range of environmental issues, from clean air and water to hazardous waste and climate change.
