Earth Day 1970 was more than a protest. It built a movement.

The Washington Post published an op-ed by Adam Rome, on how activists can lay the foundation for a broader, deeper environmental movement as we mark the 50th anniversary of Earth Day. “Earth Day’s success was measured not in the demonstration itself. Rather it created a movement with staying power, including the ability to grow stronger despite the waxing and waning of media attention,” wrote Rome.
