It's interesting to think about corn and cost.

谷物和其成本值得思考推敲
Now Michael Pollan wrote about this

迈克尔·鲍兰曾在2003年的
in an article in The New York Times in 2003.

《纽约时报》上发表过一篇文章
What he talked about was this intersection of industrialized farming,

他谈到我们处在工业化农业
technological farming with pesticides, herbicides, fertilizers,

向以杀虫剂除草剂化肥
genetically modified foods that we've all talked about before,

转基因食品为代表的技术农业的转型岔口
and the incentives brought about by the subsidies to the industry.

以及补贴对其带来的激励
He said that this led to overproduction of certain things--

这导致了某些商品生产过剩
in this case corn he was talking about--that dropped the price.

就像他说的这就导致了谷类价格下降
The farmers had to grow more to maintain their income,

由于农民耕种的作物单位面积收入在减少
because what they were growing was bringing less per bushel

加上农作物产量过高市场供大于求
because of the high, high yields that were out there,

所以农民不得不种植更多作物
