The fearsome Law of Unintended Consequences strikes again:
Most of the plantations around us were new, their rise a direct consequence of policy decisions made half a world away. In the mid-2000s, Western nations, led by the United States, began drafting environmental laws that encouraged the use of vegetable oil in fuels — an ambitious move to reduce carbon dioxide and curb global warming. But these laws were drawn up based on an incomplete accounting of the true environmental costs. Despite warnings that the policies could have the opposite of their intended effect, they were implemented anyway, producing what now appears to be a calamity with global consequences.
