From the New York Times article about the director in the Amazon:
"Now, Mr. Cameron said, he has been spurred to action, to speak out against the looming environmental destruction endangering indigenous groups around the world — a cause that is fueling his inner rage and inspiring his work on an “Avatar” sequel.
“Any direct experience that I have with indigenous peoples and their plights may feed into the nature of the story I choose to tell,” he said. “In fact, it almost certainly will.” Referring to his Amazon trip, he added, “It just makes me madder.”
Cameron brought Sigourney Weaver along this time, and both will protest the Belo Monte project in Brasilia this week. He wrote a letter to Lula, though it would seem he was denied a private meeting with him, unless it was held secretly, which I doubt.
The Belo Monte project has been in the works for a long time, and indigenous groups have fought against it since the idea came to light. It's one of the classic Amazon struggles: development to benefit Brazilians with jobs and energy vs. environmental destruction and further marginalization of indigenous groups. Despite protests against the dam, it looks as though the project is going to move forward. But with such a high profile celebrity on the ground, allied with Brazilian protesters, he just might have thrown a wrench into the process, at least temporarily.
What do you think about a big Hollywood star using his fame for this cause? Is he fighting a good fight, or is he just a gringo metido?
