In this fascinating look at the race to secure the global food supply, environmental journalist and professor Amanda Little tells the defining story of the sustainable food revolution as she weaves together stories from the world's most creative and controversial innovators on the front lines of food science, agriculture, and climate change. Climate models show that global crop production will decline every decade for the rest of this century due to drought, heat, and flooding. Water supplies are in jeopardy. Meanwhile, the world's population is expected to grow another 30 percent by midcentury. So how, really, will we feed nine billion people sustainably in the coming decades? Amanda Little, a professor at Vanderbilt University and an award-winning journalist, spent three years traveling through a dozen countries and as many U.S. states in search of answers to this question. Her journey took her from an apple orchard in Wisconsin to a remote control organic farm in Shanghai, from Norwegian fish farms to famine-stricken regions of Ethiopia. The raise to reinvent the global food system is on, and the challenge is twofold: We must solve the existing problems of industrial agriculture while also preparing for the pressures ahead. Through her interviews and adventures with farmers, scientists, activists, and engineers, Little tells the fascinating story of human innovation and explores new and old approaches to food production while charting the growth of a movement that could redefine sustainable food on a grand scale. She meets small permaculture farmers and "Big Food" executives, botanists studying ancient superfoods and Kenyan farmers growing the country's first GMO corn. She travels to places that might seem irrelevant to the future of food yet surprisingly play a critical role - a California sewage plant, a U.S. Army research lab, even the inside of a monsoon cloud above Mumbai. Little asks tough questions: Can GMOs actually be good for the environment - and for us? Are we facing the end of animal meat? What will it take to eliminate harmful chemicals from farming? How can a clean, climate-resilient food supply become accessible to all? Throughout her journey, Little finds and shares a deeper understanding of the threats of climate change and encounters a sense of awe and optimism about the lessons of our past and the scope of human ingenuity.
