As Climate Change Continues to intensify, the outlook for life on Earth often seems bleak. Yet we can find hope in the "rescue effect," nature's innate ability to persist during hard times. Like a thermostat starting the air conditioning when a room gets too warm, the rescue effect automatically kicks in when organisms are stressed. In this book, Michael Mehta Webster reveals the science behind nature's resilience, through compelling stories of species adapting to our changing world: tigers in the jungles of India, cichlid fish in the great lakes of Africa, and corals in the Caribbean. In some cases, like the mountain pygmy-possum in Australia, species may be lost without our help. We are not only observers to species declines; we are often also the cause. In choosing whether are how to help, we must navigate challenging questions about emerging technologies and the ethics of conservation. Ultimately, there are good reasons to expect a bright future. Everywhere we look, we see evidence that nature can rescue species from extinction. When nature alone is not up to the task, we can help. Combining rigorous research with gripping storytelling. The Rescue Effect provides the cautious optimism we need to help save life on Earth.
