New Hummus Among Us
Fifty-one years ago, a handful of U.S. political leaders and student activists organized the first Earth Day on college campuses. Held on April 22—midway between spring break and final exams—the event brought the public’s attention to environmental issues, and the idea snowballed. Today, Earth Day is the world’s most-observed secular holiday. An estimated one billion people in 190 countries participate in some way.
