Famine—with all its attendant suffering—has plagued humanity since the beginnings of agriculture some ten thousand years ago. Ancient Hebrew, Chinese and Greek texts speak of it, and starvation and cannibalism were the dying experiences for peoples in numerous collapsed societies, including the Mayan, Anasazi and Greenland Vikings. The last massive modern famine occurred in 1961 when 30 million Chinese perished. Then came the Green Revolution—mankind’s savior—with its vast verdant fields and bumper crops. Still, even as we profit from this miracle of man over nature, three billion people suffer each day from malnutrition. And with our world food stocks falling to all-time lows, the forces of population growth, land degradation, water decline, rising energy prices and global warming are converging into a “perfect storm” calamity, threatening to soon usher in history’s greatest famine.
