60秒科学：Narcotics-Trafficking-Slashes-Central-American-Forests
听力内容：
60秒科学节目（SSS）是科学美国人网站的一套广播栏目，英文名称：Scientific American – 60 Second Science,节目内容以科学报道为主，节目仅一分钟的时间，主要对当今的科学技术新发展作以简明、通俗的介绍，对于科学的发展如何影响人们的生活环境、健康状况及科学技术，提供了大量简明易懂的阐释。
The drug trade has devastated communities in Central and South America. Policy makers are now looking at moving away from trying to stop drug production, to trying to curb demand. If it works and narcotic producers lose power, Central America’s forests may benefit along with its people. That’s according to a new policy report in the journal Science.
It turns out that the growth of the cocaine business has led in Central America to what’s called narco-deforestation. The practice takes place in ecologically sensitive and even protected areas.
Poverty, weak governments, and illegal logging all affect forest use. But Central America has become an important bridge between the U.S. and South America’s cocaine. Forests have been slashed for roads and plane landings. And when local ranchers or timber sellers become rich with drug money, they expand their operations. Narcotic producers also develop habitat for legal agriculture that’s used to launder drug money. Government agents are bribed to turn away, and conservation groups fear entering these areas.
The study authors say that the ecological and conservation impacts of the drug trade are underappreciated and that they should inform both conservation and drug policy in the future.
