Earth is presently our only home, and we must care for it with that thought in mind. How has the U.S. government protected our environment so that people can live and work safely in an always-changing world? From Earth Day to a possible Green New Deal, this book will take a look at the laws enacted to protect our water, land, and air. The Wilderness Act and the Endangered Species Act changed how we approach and maintain our land and its wildlife; carbon taxes and climate change may alter it further.
