1Dammed There are few places on Earth as spectacular and isolated as the Amazon. But this world is currently under threat from the Brazilian government�s plans for hydro-electric dams which would flood vast areas of rainforest and wipe out local villages. Venture deep into the heart of the Amazon and you enter a world completely untouched by the 21st century, where people survive on the bounty of South America's mightiest river. Life for the Kayapo people who live here is simple, innocent and unscarred by the outside world. But soon, about 600 square kilometres of the area will be lost to the world�s third largest hydro dam, Belo Monte, displacing over 40,000 people. But as 60 Minutes� Allison Langdon discovers, these people are not going down without a fight, and they have one very powerful weapon - Hollywood. In fact, the film Avatar was based on the Kayapo tribe in the Amazon and actress Sigourney Weaver and director James Cameron have both become real-life crusaders in the fight to protect the region and its people against these hydro dams.
