A perfect storm is brewing as agriculture pioneer Cary Fowler races against time to protect the future of our food. Seed banks around the world are crumbling, crop failures are producing starvation and rioting, and the accelerating effects of climate change are affecting farmers globally. Communities of indigenous Peruvian farmers are already suffering those effects, as they try desperately to save over 1,500 varieties of native potato in their fields. But with little time to waste, both Fowler and the farmers embark on passionate and personal journeys that may save the one resource we cannot live without: our seeds. With a passion few possess, Cary sets out to build the world’s first global seed vault — a seed collection on a scale larger than any other. The vault, located in Norway, is an unprecedented insurance policy for the crop diversity of the world. In an extraordinary gesture of support, the farmers of the Potato Park become the first indigenous community to send samples of their potato diversity to the vault for safekeeping. As the stakes of maintaining a secure global food system continue to rise, adaptation will become a requisite for our own survival. How can we best maintain the diversity that still exists for our food crops? How do we create new diversity to adapt our fields to a changing climate? The answers are as complex as the system they intend to fix. And it will require a combination of efforts: from scientists, plant breeders, researchers, farmers, politicians, and even gardeners.
