Darken the night, brighten the future
On Saturday, March 29, join millions of others across the country and around the world—from Toronto to Tel Aviv—in turning off nonessential lights from 8-9 p.m. The lights out activity is part of Earth Hour, a project of the World Wildlife Fund. You'll be making a powerful statement about energy conservation and fighting light pollution—a one-two punch, plus Earth Hour has celestially-aligned to kick off National Dark Sky Week (March 29-April 4). Learn more about Earth Hour here and get enlightened about preserving the darkness here, the website of the International Dark Sky Association.
