We have one last chance to officially tell President Obama not to approve the dirty Keystone XL tar sands pipeline.

By now, we all know what will happen if we tap dirty Canadian tar sands reserves with the Keystone XL pipeline -- catastrophic climate disaster. The last public comment period on the pipeline ends this week and numbers really count. We need to show President Obama the huge political and scientific risk of approving the Keystone XL. 

The last time the State Department was accepting comments, we submitted over 1 million as a movement. And the pressure worked -- the pipeline is still not approved and the President is still on the fence about the project. Let's beat that number this time around with more than 1 million against the pipeline, and show that our movement is growing.

Submit your comment against Keystone XL, and tell Obama to be a climate champion and not a pipeline president.
