Will Organic Food Fail to Feed the World?

[Bok]

Food for hungry mouths, feed for animals headed to the slaughterhouse, fiber for clothing and even, in some cases, fuel for vehicles--all derive from global agriculture. As a result, in the world's temperate climes human agriculture has supplanted 70 percent of grasslands, 50 percent of savannas and 45 percent of temperate forests. Farming is also the leading cause of deforestation in the tropics and one of the largest sources of greenhouse gas emissions , a major contributor to the ongoing maul of species known as the " sixth extinction ," and a perennial source of nonrenewable groundwater mining and water pollution.
