In the first comprehensive biography of Douglas, Jack E. Davis explores the 108-year life of this compelling woman. Douglas was more than an environmental activist. She was a suffragist, a lifetime feminist and supporter of the ERA, a champion of social justice, and an author of diverse literary talent. She came of age literally and professionally during the American environmental century, the century in which Americans mobilized an unprecedented popular movement to counter the equally unprecedented liberties they had taken in exploiting, polluting, and destroying the natural world.

The Everglades were a living barometer of America's often tentative shift toward greater environmental responsibility. Reconstructing this larger picture, Davis recounts the shifts in Douglas's own life and her instrumental role in four important developments that contributed to Everglades protection: the making of a positive wetland image, the creation of a national park, the expanding influence of ecological science, and the rise of the modern environmental movement. In the grand but beleaguered Everglades, which Douglas came to understand is a vast natural system that supports human life, she saw nature's providence.
