She is 85, has a glittering film career behind her, and recently battled cancer, but Jane Fonda doesn't intend to slow down her activism on climate change -- the "greatest crisis ever to confront humanity" -- anytime soon. "My cancer is in remission. I've got a lot of energy. I'm ready to kick some more ass," she tells AFP backstage at the ongoing Hollywood Climate Summit. "I'm part of the Hollywood community. I don't think the Hollywood community has done enough to confront this crisis. So I'm here to encourage that," says the double Oscar-winning actor. The summit brings filmmakers together with scientists and activists, in a bid to change the industry's culture and encourage better climate messaging to global audiences. IMAGES AND SOUNDBITES
