In the first decades of the 21st century, those working to assure that earth continues to be a viable home for humanity as well as for all other life have been in a crisis regarding their purpose and direction. This is a departure from the past century and a half, when the giants of conservation and environmental protection—personalities such as John Muir, Rachel Carson, and David Brower— were certain of their cause and the actions needed to sustain it.

One of the most important and transformative mechanisms the U.S. Congress has ever created to protect the environment is under assault from the Donald Trump Administration. The National Environmental Policy Act (NEPA) ushered in the modern era of U.S. environmental law.

The National Environmental Policy Act (NEPA) plays a crucial role in the authorization and approval of more development projects than any other federal law. Proponents believe NEPA protects communities and the environment from potentially detrimental projects, while critics counter the Act prevents timely review of important infrastructure projects.
