BOSTON (AP) - Campus groups that once fought separately for divestment from fossil fuels, prisons and other industries are forming new alliances at some U.S. colleges to push their demands collectively.

BOSTON (AP) Campus groups that once fought separately for divestment from fossil fuels, prisons and other industries are forming new alliances at some U.S. colleges to push their demands collectively.

Coalitions of different movements have formed this year at Wesleyan, Tufts and Columbia universities as well as the University of Pennsylvania.

Their goal is partly to gain power in numbers, but students say their causes share common ground. For example, some point to a recent study at Columbia predicting that rising temperatures pose a health risk at prisons.

Experts say it's a new level of cooperation for campus groups that used to work separately.

The collaborations have had some success. After students staged a joint sit-in this year, the president of Wesleyan agreed to endorse divestment from the prison industry.
