Efforts to put aside vast areas of land for environmental preservation continue to stir up controversy, but none more so than the impact on impoverished people in developing nations.  A classic example is the island of Madagascar, where a pledge was recently made to increase protected areas from 4 million to nearly 15 million acres.  But according to PlanetArk.com, this is having a profound effect on many of the island’s 17 million people who live on less than a dollar per day, and rely on firewood from the wild forests, or burn sections in which to plant rice.  Government officials say eco-tourism will help provide more income, but that’s little immediate comfort to many who have farmed in these areas for generations.
