Fifty-five years ago, the first Earth Day started as a grassroots, activist effort to raise awareness about air pollution, toxic drinking water and the effects of pesticides. On April 22, Earth Day 2025 brings with it some good news for the planet as a growing number of large companies disclose their carbon emissions.

April 22 is Earth Day. Several organizations in the metro Atlanta area participated in projects or hosted events in honor of the day.

The first Earth Day was celebrated in 1970, making this year's festivities the 55th annual festival. For the first Earth Day, 20 million people went to inaugural events at schools, universities and other public areas around the country to protest for cleaner water, air and land.
