When was the first environmental policy?

The first significant environmental policy in the United States is often considered to be the National Environmental Policy Act (NEPA), signed into law on January 1, 1970. NEPA established a framework for environmental impact assessments and required federal agencies to consider the environmental effects of their actions. This marked a pivotal moment in U.S. environmental policy, paving the way for subsequent legislation aimed at protecting Natural Resources and promoting sustainable practices.
