Today is Earth Day, the largest secular observance in the world. Earth Day went global in 1990 with people celebrating from 140 countries - today, more than a billion people participate every year. We hope everyone has a wonderful day, let’s show some love to our planet!
The first Earth Day was in 1970. What’s changed since? Our population has doubled. We’re emitting 2.6 times more CO2. Sea levels have risen 12 centimeters. But the world has also changed for the better. See how our actions since 1970 have added up. What’s changed?
