The clock is ticking on one of the greatest potential disasters in the history of our species and one man leads a worldwide crusade to avert it. Crop diversity pioneer Cary Fowler travels the world, educating the public about the dire consequences of our inaction. The world's agriculture - and it's fate - are dependent on the ability of plants to adapt to changes in climate, pests and disease - but today's crops around the globe are grown from human-engineered seeds and have lost nearly all their diversity and ability to naturally adapt. Could one massive infestation of fungus, blight or insects cause all the world's corn, wheat or lettuce to die? Is modern agriculture setting the stage for economic disaster, food riots, and global starvation? Dr. Fowler is the head of an international consortium to store seeds from every agricultural plant in the world. But is his farsighted program enough to save humanity from annihilation?
