Because agricultural chemicals are usually sprayed over large areas, it's hard to avoid polluting nearby water.

由于农用化学品通常大面积喷洒，很难避免污染附近的水。

While emissions from destroying the crops are small, some critics say more cover crop planting will increase the use of farm chemicals.

虽然处理农作物的碳排放量很小，但一些批表示，植越作物，农用化学品的使用也会随之增加。

And that promotion often comes from places like the pharmaceutical, agrochemical, and home aquarium industries — industries which promote only those things from which they can make a profit, like drugs, fertilizers, aquarium supplements, and other heavily engineered chemical cocktails.

而这推广往往来自制药、农用化学品和家庭水族箱行业等地方——这些行业只推广那些他们可以从中获利的东西，比如药物、肥料、水族箱补充剂和其他大量工程化的化学鸡尾酒。
