Many of us have been inspired by the strong organizing by environmentalists and environmental justice forces that succeeded in blocking the construction of the Keystone XL pipeline.

To provide a little background on the Keystone XL campaign: The Keystone XL is a new oil pipeline that was proposed by the Canadian oil and gas company, TransCanada, that would carry tar sands oil from Alberta, Canada to Texas. The extraction of tar sands is massively polluting. Tar sands extraction sites in Canada have devastated the surrounding environment and communities, in particular in Native communities. The potential pipeline would expand that damage; it would add new risks to the ecosystems and communities along the proposed pipeline. According to leading climate scientist, James Hansen, the building of the Keystone XL pipeline and the commitment of the United States to exploiting the rest of the remaining Canadian tar sands would be "game over" for the climate.
