The drug trade has devastated¹ the communities in central South America. Policy-makers are now looking at moving away from trying to stop drug production to trying to curve demand. If it works,and all kinds of producers lose power, central america's forests may benefit alone with it's people. That's according to a new policy report in the Journal Science.

It turns out that the growth of cocain business has led in Central Americal to what is called narco deforestration. The pratice takes place in econologically sensitive and even protected areas. Poverty, weak governments and illegal logging all affect forest use. But central America has become an important brige between the US and South America's Cocain. Forests have been slashed² for roads and plane landings. And when local rigion's timber sellers become rich with drug money, they expand the operations. All kind of producers also develop habitate for legal agriculture that's used to laudrary drug money.

Government agents are brave to turn away and conservation groups are fear entering these areas.

The study auther says that the ecological³ unconservation impacts the drug trader under appreciated, and they should imform but conservation and drug policy in the future.
