How safe is the future of the world’s food? This documentary explores a growing crisis in world agriculture. Plant breeding has created today’s crops, which are high yielding but vulnerable to disease and insects. To keep crops healthy, breeders tap all the genetic diversity of the world’s food plants. But that rich resource is quickly being wiped out. (NFB)
