Los Angeles, Nov 22: Leonardo Dicaprio is urging elected officials to reduce American dependence on oil and slow global warming. The 29-year-old actor and conservationist narrated an online film called 'Global Warning' as part of an Internet campaign organized by Global Green USA, an affiliate of Green Cross International.

The campaign, which began Thursday, asks people to oppose the energy bill that's under debate in Congress by signing a "pledge of allegiance to American energy independence." The bill would provide USD 23 billion in tax incentives and includes measures to produce more coal, oil, natural gas and nuclear power.

The 'Titanic' star said people should use energy more efficiently by supporting renewable energy sources such as wind and solar power.

In the film, Dicaprio criticizes elected officials who "gained too much money and power off our addiction to oil" as being resistant to change. "We must demand a separation between oil and state," he says. "We can vote for leaders who care about protecting your health, the air and the environment."

Dicaprio owns two hybrid cars powered by both gasoline and electricity, said Global Green president Matt Petersen, who worked with Dicaprio on the campaign. Bureau Report
