Since 2000, the earth’s forest cover has shrunk by 13 million acres each year, with annual losses of 32 million acres far exceeding the regrowth of 19 million acres. Restoring the earth’s tree and grass cover protects soil from erosion, reduces flooding, and sequesters carbon.
Global deforestation is concentrated in the developing world. Tropical deforestation in Asia is driven primarily by the fast-growing demand for timber and increasingly by the expansion of oil palm plantations for fuel. In Latin America, the fast-growing markets for soybeans and beef are together squeezing the Amazon. In Africa, the culprit is mostly fuelwood gathering and land clearing for agriculture…

Hundreds of millions of people in Africa depend on it, as do hundreds of millions more in Asia and Latin America. According to the UN’s Food and Agriculture Organization, cassava accounts for a third of Africans’ total caloric intake.
It may soon become even more important: New research suggests it is ideally suited to withstand drought and climate change…
