A thoughtful exploration of how humans have endangered the Earth but can pull it back from the brink, as told by a renowned conservationist This personal and thoughtful book by renowned Kenya conservationist David Western traces our global conquest from Maasai herders battling droughts in Africa to the technological frontiers of California. Western draws on a half century of research in the savannas and his own life’s journey to argue that conservation is not a modern invention. The success of all societies past and present lies in conservation practices, breaking biological barriers and learning to live in large cooperative groups able to sustain a healthy environment. Our ecological emancipation from nature enabled us to expand our horizons from conserving food and water for survival to saving whales, elephants, and our cultural heritage. In the Anthropocene, our scientific knowledge and modern sensibilities offer hope for combating global warming and creating a planet able to sustain the wealth of life, but only if we use our unique cultural capacity of cooperation to plan our future.
