Why is important to celebrate Earth Day?

The first Earth Day took place in 1970, when 20 million people across the United States participated in events at schools, universities, and public spaces. This movement was spurred by growing concerns over climate change and pollution.

The event was organized by Dennis Hayes, who was a student at the time and now serves on the board of Earthday.org. Around one in ten Americans joined the cause in 1970, advocating for cleaner air and water. Their efforts led to the establishment of the Environmental Protection Agency, the Clean Air Act., and the Clean Water Act.
