耶鲁公开课。全球人口增长问题。
问题在于,面对全球每年1.2%的人口增长,农民需要种植多少粮食才能满足人类的需求?
The question is, how much do they need to grow to keep abreast of the growth in the world’s population of about 1.2% a year?
人口的增长虽然只是食品需求增长的部分原因,但是人口增长所带来的全球变暖、长期气候变化等问题仍然给农业带来了巨大的威胁。
While population growth accounts for only a modest part of the growing demand for food, it can contribute to global warming, and long-term climate change can threaten agriculture.
