DiCaprio's grunge version speaks

After his performance at the Rock-am-Ring Festival in Germany, Jared Leto announced that he "hoped that people would take more interest in saving the planet."

"You can get somebody to turn off the light or to unplug an appliance or to plant a tree," he said.

"I think it's a wonderful thing, we've moved beyond the days of tree-hugging hippies being the example of environmentalism around the world," Leto said.

"It's the responsibility of not only hippies, but all of us. I'm a closet hippy anyway - hence my long hair." He didn't! He did.

Leto also said that he hoped that environmental concerns would become an obvious choice for everyone. Team Leo.
