What major piece of legislation forced government agencies to prepare environmental impact statements?
Wilderness Act of 1964
Clean Air Act of 1963
National Environmental Policy Act of 1969
Clean Water Act of 1977

The major piece of legislation that mandated government agencies to prepare environmental impact statements is the National Environmental Policy Act of 1969 (NEPA). This groundbreaking law established a nationwide framework for considering the environmental consequences of federal actions, ensuring that potential adverse effects are evaluated before projects are approved. NEPA has become a cornerstone of environmental policy in the United States and serves as a model worldwide.

In practical terms, NEPA requires federal agencies to assess the environmental impacts of their proposed actions, including large construction projects and policy changes. If you’re ever curious about how this process unfolds, you’ll find that public involvement is a key part, as communities can voice their concerns and contribute to decision-making. It’s an excellent example of how environmental stewardship can be integrated into government planning!
