Sterling College in Vermont announced on Tuesday it will soon become the third college in the United States to divest its endowment from 200 fossil fuel companies identified by the environmental group 350.org. Unity College in Maine and Hampshire College in Massachusetts were the first two schools to divest. Divestment campaigns are ongoing on more than 200 other campuses. "I think it’s no surprise, really, that young people are starting to say, ’We’ve got to spend another 60, 70 years on this planet. We better do something fast,’" says Bill McKibben of 350.org. "And that something means standing up to the fossil fuel industry that’s been in the way of rational change for a quarter-century now." McKibben is helping organize a Presidents’ Day rally against the Keystone XL pipeline later this month, one he predicts will be the "biggest climate rally probably ever" in the United States.
