Well, that's the retort he gave when asked by a journalist if he flew on a gas guzzling jet to arrive at the premier screening of his new Eco-doco, The 11th Hour, in Cannes, France. He later noted that he tries to fly commercial flights as much as possible, and that the snarky remark about railing it 'over the pond' was an irritated reaction to the media focus on the supposed inconsistency in the private lives of so called eco-celebrities. "We're all trying the best we can, truly, we really are," he said. "Attacks on Al Gore for example I think are misdirected. Don't shoot the messenger, you know what I'm saying? If you're going to attack somebody on the way they conduct their life, let's talk about the big picture, let's see what big oil companies are doing." And it is that bigger picture that his movie is apparently focussed on, "Certainly in the United States we are the ones that should set an example for the rest of the world. We are the most powerful democracy on the planet and we're also the largest polluters simultaneously," he said. DiCaprio said, despite the film's tone, he was optimistic about humanity's fate. "I'm happy to be a part of this generation that talks about an issue that affects so many generations after us like global warming does. It's probably the biggest movement in human history, if done right." ::The 11th Hour, via ABC.
