Thousands of people rallied outside the White House on Sunday calling on President Obama to reject the Keystone XL tar sands oil pipeline. The Keystone XL would carry crude oil from Alberta’s tar sands to the Gulf Coast, a project opponents say would produce lethal levels of carbon emissions while endangering communities along its path. Obama now faces a decision on the pipeline’s approval after delaying it until after the 2012 election. The group 350.org, as well as other environmental organizations, say the rally marked the first in a series of actions that will culminate in another major protest against the Keystone XL on President’s Day, February 18, 2013.
