You probably know April 22nd as Earth Day, a time to celebrate our planet and think green. But did you know its roots are deeply tied to a massive oil spill and a senator's vision for environmental change?
Earth Day is trending because millions are celebrating it today, April 22nd, but many don't know its powerful origins.
While it's a global event now, Earth Day began as a grassroots movement in the United States, fueled by growing public concern over pollution and environmental degradation in the 1960s.
