The combined effects of those trends and the political tensions they generate point to the breakdown of governments and societies. Yet I, too, have resisted the idea that food shortages could bring down not only individual governments but also our global civilization.B I can no longer ignore that risk. Our continuing failure to deal with the environmental declines that are undermining the world food economy forces me to conclude that such a collapse is possible.C As demand for food rises faster than supplies are growing, the resulting food-price inflation puts severe stress on the governments of many countries. Unable to buy grain or grow their own, hungry people take to the streets. Indeed, even before the steep climb in grain prices in 2008, the number of failing states was expanding. If the food situation continues to worsen, entire nations will break down at an ever increasing rate. In the 20th century the main threat to international security was superpower conflict; today it is failing states.D States fail when national governments can no longer provide personal security, food security and basic social services such as education and health care. When governments lose their control on power, law and order begin to disintegrate. After a point, countries can become so dangerous that food relief workers are no longer safe and their programs are halted. Failing states are of international concern because they are a source of terrorists, drugs, weapons and refugees(难民), threatening political stability everywhere.E The surge in world grain prices in 2007 and 2008and the threat they pose to food securityhas a different, more troubling quality than the increases of the past. During the second of the 20th century, grain prices rose dramatically several times. In 1972, for instance, the Soviets. I recognizing their poor harvest early, quietly cornered the world wheat market. As a result, wheat prices elsewhere more than doubled, pulling rice and com prices up with them. But this and other price shocks were event-drivendrought in the Soviet Union, crop-shrinking heat in the U.S. Corn Bel
