"Dispossessed peasants slash-and-burn their way into the rain forests of Latin America, hungry nomads turn their herds out into fragile African rangeland, reducing it to desert, and small farmers in India and the Philippines cultivate steep slopes, exposing them to the erosive powers of rain. Perhaps half the world's billion-plus absolute poor are caught in a downward spiral of ecological and economic impoverishment. In desperation, they knowingly abuse the land, salvaging the present by savaging the future."
