Leonardo DiCaprio, Chace Crawford and Justin Long are using their celebrity influence to encourage people to start using social networking as a way to lobby for an environmental bill in Washington.

This Is Our Moment is a new online campaign that asks people to, among other things, flood the inboxes of Senators who have the power to pass the Clean Energy, Jobs and American Power Act. The campaign is powered by The Natural Resource Defense Council Action Fund, of which Leo is a trustee.

The campaign's website, which features a star-studded PSA, reads:

"Everyone knows we have a dependence on oil we buy from countries that don't share our values. This threatens our security and our integrity. And it needs to stop. We know it does. Still, we've seen our dependence on foreign oil grow and pollute the air we breathe and endanger our planet. But we can change that. Now.

There's a bill in the Senate that will break foreign oil’s stranglehold on our country, reduce carbon pollution, and create jobs right here in America—good jobs that pay well and can't be outsourced.

It’s one of the most important pieces of legislation of our time. It's a clean energy bill. And it’s been a long time coming."
