Times have changed since the first Earth Day, when a U.S. senator from Wisconsin managed to funnel the era’s activism into the historic gathering that put the rising challenges of the environment on the nation’s agenda.

As the 40th anniversary of Earth Day approaches this April 22, the Earth Day legacy is more important than ever.
