Anyone who has paid much attention to environmental movements and conservation will know that 'conservation' is often a guise for colonialism. It is estimated that 20 million people worldwide have been evicted from their homelands for 'conservation' /national parks -14 million of these people are Africans. "The Batwa and maybe soon the Ogiek are examples of how indigenous peoples close to nature are being systematically expelled from their ancestral lands. They become refugees of nature conservation efforts which are often gimmicks or have ulterior motives rewarding mining, water, timber, or other corporate industries."
