"Overproduction and intensive use is leaving much of the world's farmland barren. Looks at farmers in Australia, Indonesia, West Africa, and the United States who are rediscovering traditional agricultural practices and using science and technology to work with nature, rather than conquer it. Topics include: use of organic vs. chemical fertilizers, natural insect control vs. pesticides, crop rotation, reforestation and replanting of indigenous species to combat soil erosion/depletion; plant biotechnology to produce virus resistant strains." . . . .
