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 causing starvation and rioting, and the accelerating effects of climate change are affection famers 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 files. 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.
