英语语法分析

An obvious example is bioprospecting, the perusal of nature's genetic library for new food, medicine and pesticide ingredients.

一个典型的例子就是生物勘探，为了寻找新的食物，药品和对除害剂，会细细查看大自然基因库。

But bioprospecting has done almost nothing to raise the value of standing forests. This is partly because of difficulties in attaching property rights to species.

但是生物勘探对现有森林的价值提升几乎没有贡献，部分因为为物种加上产权是比较荒唐的。
