It is striking how tar sands and the Keystone XL pipeline have brought people together around concern for our water and climate. In Canada, communities such as the Athabasca Chipewyan First Nation and the Beaver Lake Cree are fighting to protect their health, waters, and lands from the leaking dams of toxic waste and the destruction of strip-mining for tar sands. In British Columbia, over 100 First Nations have taken a strong stand against tar sands pipelines crossing their land and waters. In Nebraska, ranchers such as Randy Thompson — who was arrested with me at a White House protest this week — are saying no to the Keystone XL tar sands pipeline. Water and climate walk hand in hand with threats as big as the dirty energy path of tar sands. A dirty energy future means trading our water for tar sands, and that is not a choice any of us want to make.
