Mark Hertsgaard previews the endangered food list of the future:
Three grains—wheat, corn, and rice—account for most of the food humans consume. All three are already suffering from climate change, but wheat stands to fare the worst in the years ahead, for it is the grain most vulnerable to high temperatures. That spells trouble not only for pasta but also for bread, the most basic food of all.
Since wheat is a cool-season crop, the data doesn't look good:
By 2050, scientists project, the world’s leading wheat belts—the U.S. and Canadian Midwest, northern China, India, Russia, and Australia—on average will experience, every other year, a hotter summer than the hottest summer now on record. Wheat production in that period could decline between 23 and 27 percent, reports the International Food Policy Research Institute (IFPRI), unless swift action is taken to limit temperature rise and develop crop varieties that can tolerate a hotter world.
Hertsgaard also explains how the fossil fuel industry is gobbling up American farmland for fracking, which may be poisoning our water supply as well.
