Genetic resources Forests are the main home of Earth's species. While covering only 6% of the planet's land surface, tropical forests contain at least 50%, possibly 70% and conceivably 90% of all species. ½ km2 of Malaysia's forests can feature as many tree and shrub species as the whole of the United States and Canada, while a single bush in Peruvian Amazonia has revealed as many ant species as in the British Isles. Norman Myers
Growing more crops and trees per acre leaves more land for Nature • We cannot choose between malnourished children & saving endangered wild species • Without higher yields, peasant farmers will destroy the wildlands and species to keep their children from starving • Sustainably higher yields of crops and trees are the only visible way to safe both • Dr. Norman Borlaug
