The Story of Earth Day
How Earth Day Began
The idea for Earth Day started in 1969. A peace activist named John McConnell suggested a day to honor Earth. He wanted it to be a day for peace, observed on the first day of spring. The United Nations supported his idea.
A month later, a US Senator named Gaylord Nelson had a similar idea. He wanted to hold a nationwide "teach-in" about the environment. He asked a young activist, Denis Hayes, to help organize it. They decided to call the event "Earth Day."
The First Earth Day in 1970
The first Earth Day was held on April 22, 1970. It was a huge success! More than 20 million people in the United States joined in. They took to the streets to protest pollution and demand action for the environment. This event helped create new laws to protect our air and water.
Earth Day Goes Global
In 1990, Denis Hayes helped make Earth Day an international event. People in 141 countries took part. Today, Earth Day is celebrated by over a billion people in 193 countries. It is coordinated by a group called Earthday.org.

Flora MacDonald, a Canadian politician, officially started Earth Day Week. She planted a tree and asked other politicians to support an annual Earth Day across Canada. People celebrated by learning about the environment. They also picked up trash and planted trees.
Why April 22?

Senator Nelson chose April 22 to get the most students involved. This date avoided school exams and spring breaks. It also didn't conflict with major holidays like Easter. The weather was usually good enough for outdoor events.
April 22 is also close to the birthday of John Muir. He was a famous conservationist. Many parks celebrate his birthday and Earth Day together.
