Which agency is responsible for protecting and enhancing the environment in the U.S.?

The Environmental Protection Agency (EPA) is the agency responsible for protecting and enhancing the environment in the United States. Established in response to growing concerns about pollution and environmental degradation, the EPA's mission encompasses regulating air and water quality, managing waste, overseeing chemical safety, and ensuring compliance with federal environmental laws. The agency conducts research, sets standards, and works collaboratively with state and local governments, businesses, and communities to foster a cleaner, healthier environment.

The other agencies listed do not focus primarily on environmental protection. The Federal Bureau of Investigation (FBI) deals with national security and federal law enforcement issues, while the Occupational Safety and Health Administration (OSHA) is focused on workplace safety and health regulations to protect workers. Meanwhile, the Federal Trade Commission (FTC) concentrates on consumer protection and antitrust laws, ensuring fair competition in the marketplace. Each of these agencies has distinct responsibilities, highlighting the specialized function of the EPA in environmental matters.
