As the world continues to grapple with intensifying climate change, the situation often feels hopeless. In his groundbreaking debut, Michael Mehta Webster proves that hope can be found in nature itself. The natural world has a series of systems--rescue effects--that automatically activate to help organisms when their environment changes. The Rescue Effect illustrates how we can use this natural resiliency to help reverse climate change. The Rescue Effect details what scientists are finding as they dig deeper into how nature rescues species on its own. These rescue effects are revealed in compelling stories of species that are adapting to the changing world--including tigers in the jungles of India, cichlid fish in the great rift lakes of Africa, and mountain pygmy-possums in the snowy mountaintops of southeastern Australia. At the center of each story, people play a significant role. Rescuing our environment is not passive, and Webster shows that it takes people working in concert with nature to reverse climate change. Combining rigorous research and gripping storytelling, The Rescue Effect provides the cautious optimism we need to confront our greatest challenge.
