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 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.
