Environmental legislation refers to laws and regulations designed to protect the environment and public health. These laws aim to control pollution, conserve natural resources, and promote sustainable practices. They can cover various areas, including air and water quality, waste management, and wildlife protection. Governments at different levels, such as local, state, and federal, create and enforce these laws. In the United States, key pieces of legislation include the Clean Air Act and the Clean Water Act. International agreements, like the Paris Agreement, also play a crucial role in addressing global environmental issues.
