Which of the following was an important result of the National Environmental Policy Act of 1969?

The National Environmental Policy Act (NEPA) of 1969 was significant because it established a framework for environmental impact assessments for federal projects. One of its most important results was the creation of the Environmental Protection Agency (EPA) in 1970. The EPA was formed to consolidate and enforce national pollution control laws and regulations, reflecting a growing commitment to environmental protection and sustainability.

While the other options represent important environmental legislation and initiatives, they were either enacted prior to NEPA or were not direct results of it. The Clean Air Act and the Federal Water Pollution Control Act were established earlier and were later amended, while the Endangered Species Act came about in 1973, following the establishment of the EPA. Thus, the correct emphasis is on the establishment of the EPA as a fundamental outcome of NEPA, marking a major step in the federal government’s role in environmental regulation and oversight.
