Most plants will be lost from the topical rain forest which is the foundation of our food supply. Explores various methods of saving plants: habitat preservation, virus-resistance, synthetic seed, and gene engineering. For if there is to be a future for genetically engineered crops, we must insure the safety of "green" genes not yet lost.
