Feed the world

from Financial Times:
Rather, as the world’s affluent grow in number, particularly in China, desire for more meat and dairy products has diverted cereals to feed animals, further straining food supply. Volatile oil prices afflict farmers’ bottom lines; and now, with the advent of subsidised biofuels, when oil prices rise, food becomes more attractive as an alternative fuel, leaving less to nourish the poor.

This has long been a controversial subject. Now, five new publications wade into the fray, each with theories about the problem’s sources and potential solutions.
