Scientists have been able to dramatically increase the yields for oil palm trees, a crop with a global market.
科学家们已经能够极大地增加位居全球市场前列棕榈树的出油量;36K#RZbDXx|
Oil palms grow in the tropics, so that should mean more profit from less land, helping to protect tropical forests.
棕榈树在热带地区才可以种植,所以少量土地即可带来更大的利润,而且还能有助于保护热带森林e-&m3ZEo^XtZno%
Good news, right?
好消息,对吧?
But in an article in the journal Science, researchers show how the increased yield could in fact lead to even more tropical destruction.
但是在科学期刊上登载的一篇文章中,研究人员指出棕榈油产量的提升实际上会导致更大的热带破坏I[W5~a6ewvxu~*)uFS
Because as the value of palm oil planting increases, farmers could want to plant on even greater tracts of land.
因为随着棕榈油加工厂的增加,农民就会产生在更多的土地上更大面积种植的想法spFX+M3mPIEh)0c,K
Which is bad news.

But higher yields could make oil palm attractive to planters in those regions, leading to even more tropical forest destruction.
但是更高的产量会吸引这些地区的种植者们,造成更多的热带森林遭到破坏1]ZgGZB-_&T0Z)p
To prevent these developments, the researchers write that policy makers need to be aware of and plan for the unintended negative consequences of technical advances.
