WASHINGTON – On Sunday, February 17, thousands of Americans will gather on the National Mall to make #ForwardOnClimate the largest climate rally in history, calling for rejection of the mammoth Keystone XL pipeline and limits on power plant carbon pollution to prevent disastrous climate change.

"Join this historic event to make your voice heard and show President Obama we can't afford to wait any longer for strong climate action." Said organizers in a statement.

Several American Indian leaders stand in opposition with environmentalists against the Keystone XL pipeline. The proposed pipeline coming down through the Plains states has caused great concern, particularly among the Oglala in South Dakota.

TransCanada's proposed pipeline route is right though the Pine Ridge and Rosebud reservations. It will cross the Oglala Sioux Rural Water Supply System in two places.

Several dozen American Indians are expected to attend the #ForwardOnClimate rally. "From rejecting the toxic Keystone XL tar sands pipeline to limiting carbon pollution from our nation's dirty power plants and firing up our clean energy economy, President Barack Obama's legacy will rest squarely on his response, resolve, and leadership in solving the climate crisis. That's why the Forward On Climate Rally will feature critical action, inspiring speakers, and a march to the president's doorstep to show him that we can't afford to wait any longer." Organizers stated.
