Thousands of environmentalists marched outside the White House on Sunday, armed with banners and signs, chanting and voicing their opposition against the proposed Keystone XL pipeline.

The rally, organized by 350.org, calls for U.S. President Barack Obama to show his commitment to the environment by rejecting the pipeline project, which would run from Alberta to Texas.The demonstration followed a “Do the Math” climate event at Washington, DC’s historic Warner Theater earlier in the day.

"Do The Math" is a 21-city nationwide tour by 350.org, headlined by 350 co-founder Bill McKibben and author Naomi Klein, and is designed to galvanize the climate justice movement in the wake of the election. The tour is helping to launch an unprecedented campaign to cut off the fossil fuel industry’s financial and political support by divesting our schools, churches and government from fossil fuels.

Daniel Kessler with 350.org told CTV News on Sunday that the White House rally was one of a number of stops on a tour across the U.S., talking about climate change and environmental concerns.

“We broke 17,000 temperature records around the globe this year. What we’re seeing is really extreme weather and really extreme temperature. “We’re seeing what the scientists are predicting around climate change,” Kessler said.

“The pipeline would lead to huge amounts of emissions and make the situation worse.”

The "Do the Math" tour picks up where Bill McKibben’s landmark Rolling Stone article left off, and everyone who comes will be asked to join a growing movement that is strong enough to stand up to the fossil fuel industry.

Emily James spent more than a year embedded in activist groups such as Climate Camp and Plane Stupid to document their clandestine activities. With unprecedented access, "Just do It" takes you behind the scenes of a community of people who refuse to sit back and allow the destruction of their world.

Torpedoing the tired cliches of the environmental movement, "Just Do It" introduces you to activists who super-glue themselves to bank trading floors, blockade factories and attack coal power stations en-masse, despite the very real threat of arrest.

The film is a story of people standing up for what they believe and making themselves heard, and it needed to be told without the creative constraints of traditional production models or the editorial control of big investors. A truly independent project, "Just Do It" was made possible through 500 crowd funders, an army of over 100 volunteers, a slate of indie film giants and a handful of foundation grants.

On April 30, in preparation for May Day, Occupy.com will host a free 24-hour screening of the full-length film. Be sure to tune in!
