Los Angeles, Nov 25 (IANS): Actor Mark Ruffalo, who's also an environmental activist, will narrate a film titled "Dear President Obama", which is about Barack Obama's energy and climate change policies.

Ruffalo, who is known to oppose the process of hydrofracking to extract natural gas, will also be the executive producer of the project, reports hollywoodreporter.com.

“When you have the president saying that climate change is absolutely for real and we must do something about it, and then in the next breath he says we must start drilling in the Arctic circle even, there’s a huge disconnect, a cognitive dissonance. His own scientists are telling him we have to keep that carbon in the ground otherwise we are doomed,” Ruffalo said.

“Dear President Obama” will be directed by Jon Bowermaster.

“The film will implore President Obama to stop this drill, baby, drill, all of the above energy policy that he has taken our country on. You can’t have it both ways. You can’t keep pushing to take all the carbon out of the earth, which will be burned, while at the same time saying you believe in climate science,” he said.

“Dear President Obama” will look at the health impacts of hydrofracking, scientific research on global warming and what can be done to move the US to renewable sources of energy.
