The global climate movement claimed an historic victory last week.
US President Barack Obama rejected the Keystone XL tar sands pipeline, four years to the day after 15,000 protesters gathered to make a statement against it at the White House.
This is the first time a national leader has blocked a venture in fossil fuel specifically because of its predicted environmental effects. 350.org, who have played a significant part in the campaign against Keystone XL, say this sets an example for climate action going forward.
First Nations in Canada, where tar sands are being extracted, was where the movement against Keystone began, before expanding to include the voices of farmers, ranchers, tribal nations and citizens along the pipeline route.
The pipeline would have been used to transport 830,000 barrels per day of tar sands oil through the United States to be burned.
