Food has become more plentiful and affordable, especially in the developing world, where calorie availability has increased by 40% per person over the past 40 years, while food prices have more than halved. Consequently, the proportion of hungry in the Third World has dropped from 50% in 1950 to less than 17% today, while worldwide incomes have increased more than three-fold.
食品更丰富，价格也更便宜了，尤其是在发展中国家，其人均卡路里的可提供量在过去40年间增加了40%，而食品的价格则下降了一半多。其结果是，第三世界中面临饥荒的人口比例从1950年的50%下降到了今天的17%，而全世界的收入则增加了三倍多。
