To Save the Earth looks at the lives of four extraordinary Americans who fought to save our earth. John Muir, a pioneer of conservationism, was the founder of our national park system. Rachel Carson, biologist and author, educated our country about the effects of pesticides and chemical waste. David McTaggart, the organizer of Greenpeace, introduced nonviolent protest into the struggle, while Dave Foreman, cofounder and former leader of the activist group Earth First!, shook up a movement that had grown complacent.
