According to the BBC, "The Brazilian government says it took the images to prove the tribe exists and help protect its land" from illegal logging operations.
Limbaugh further stated, "Wait a minute. Why do we have to help protect the land of this tribe? Aren't they the essence of purity, according to the environmentalist communists? ... Why do we need to protect their land? They're doing a better job of it than any of us ever could protect our land. ... I mean, I'm sure these people--not only don't they have to get rid of their incandescent light bulbs and go to these compact fluorescents, they don't have light bulbs. They don't have electricity. They don't have running water. This is the ideal. These people need to be contacted. We need to learn from this civilization, because this is where we're all headed if the extreme environmentalist communists get their way."
