Who's right?

60 Minutes reports that the Kenyan government is driving people from the lands to which the government earlier gave them "absolute" title. The claim is that expanding population and farming is threatening the great wildebeest and zebra migration by destroying a forest which feed the Mara River. I have to wonder who's been buying off the state of Kenya to turn on its own people. How bad is the threat to the wildlife? And what do we do for the people? It's pretty clear that environmentalists place a higher value on animals and trees than on human beings, but my guess is that economic development would level off the population growth and free more land for wilderness, but environmentalists are more opposed to industry than to people.
