华盛顿的关心世界研究所所长雷士特·布朗说,由于到2050年时,全世界的人口将增加一倍而达到约100亿人,那时如要依靠科学想出办法,从泥土中长出更多粮食,科学的实力将明显不足,因而地球上将出现土地荒芜、井泉干涸和人类有史以来最大的饥荒。具体说来,布朗认为到2030年时,印度将每年进口4,400万吨粮食以供应它的15亿人民。同时,不断繁荣和工业化的中国需要为它的16亿人民向国外购买2亿吨粮食。这个数量相当于世界各国目前的总输出量。其结果是这种情况将成为粮食价格中的一枚尖钉,能激发起非洲、拉丁美洲和其他贫穷地区的“大规模社会
Rethstone Brown, director of Washington’s Institute for World Affairs, said that by 2050, the world’s population will double to about 10 billion. At that time, if science relies on solutions, Out of more food, the strength of science will obviously be insufficient, so there will be barren land on Earth, Jingquan dry up and humanity’s biggest famine in history. Specifically, Brown believes that by 2030 India will import 44 million tons of food each year to supply its 1.5 billion people. Meanwhile, China, booming and industrialized, needs to purchase 200 million tons of grain for its 1.6 billion people abroad. This amount is equivalent to the current total output of all countries in the world. The result is that this will be a sharp spike in food prices that will inspire "large-scale societies in Africa, Latin America and other impoverished regions
