A more thorough explanation:

EPA

EPA stands for Environmental Protection Agency. It is a government agency in the United States that is responsible for protecting human health and the environment by enforcing laws and regulations related to air and water quality, hazardous waste, and other environmental issues.

• The EPA sets limits on the amount of pollutants that can be released into the air and water by factories and other sources.
• The EPA conducts research and provides information to the public about environmental issues.
• The EPA works with state and local governments to enforce environmental laws and regulations.

These examples illustrate how the EPA works to protect the environment and human health by regulating and enforcing laws related to pollution and other environmental issues. By setting limits on pollutants and working with other government agencies, the EPA helps to ensure that the air and water we rely on are safe and healthy for everyone.
