When is Earth Day celebrated?

Earth Day is April 22. Because events and festivals usually take place on a weekend, Earth Day is often observed on the weekends before or after April 22. Many communities also celebrate Earth Week or Earth Month with a series of environmental activities in April.

Who founded Earth Day?

Gaylord Nelson, a former U.S. Senator.

Why was Earth Day created?

By the early 1970s, many Americans were upset over the damage human beings were causing to the Earth and its environment. Due to the use of leaded gasoline and lack of air filters or emissions requirements for vehicles and factories, a tremendous amount of pollution was being released into the environment. Earth Day was launched internationally in 1990 when 200 million people in 141 countries participated in the event.

Many Americans refused to accept the notion that pollution was a merely a reflection of the prosperity of the United States. Lead by Mr. Gaylord Nelson, the founder of the first Earth Day, many Americans across the country decided to conduct a demonstration on April 22, 1970, to voice their displeasure and to try to change government and business practices so that they were less harmful to the environment.

Did the Earth Day observances in the early 1970s get the federal government and the general public to take more notice of environmental issues?

Yes, the first Earth Day observances helped to influence the Federal Government to develop and implement the Clean Air Act, the Clean Water Act, and the Endangered Species Act. Each year, the number of people observing Earth Day continues to grow. Earth Day is also observed in many foreign countries as well.

What can I do to celebrate Earth Day?
