An important book argues that conservationists who focus on creating nature preserves are undermining their own cause. To truly protect biodiversity, environmentalists must support the global struggle of peasant farmers for human rights, land, and sustainable agriculture. In any discussion of biodiversity and species extinction, someone insists that overpopulation is the problem. More people equals more farms equals less wilderness equals more extinctions. Life is a zero-sum game: you can have people and farming OR wildlife and biodiversity, but not both.
