Earth Day

April 22

Earth Day is celebrated around the world on April 22. It is a day to celebrate the environment and raise awareness about its problems. Earth Day is not an official, national holiday, but it is celebrated around the world with events in schools and parks.

Gaylord Nelson, a senator from Wisconsin, founded Earth Day in 1970. Nelson wanted to pass legislation to protect the environment, and he decided to raise awareness about the issue using some of the strategies of the Vietnam War protesters. He organized a gathering of 20 million people who spent the day cleaning creeks, recycling tin cans, and learning how they can help protect the environment.
