April 22 is a day to celebrate the Earth. Founded by US Senator Gaylord Nelson, the Earth Day was first celebrated on April 22, 1970 in the United States. 20 million people and thousands of local schools and communities participated in the first Earth Day. In 1990, the first official International Earth Day was celebrated. About 200 million people from 141 nations took part in a celebration of environmental conservation.
The goal of the Earth Day is to promote environmental awareness, highlight growing concern over pollution of the air, soil, and water, and to call for the protection of our planet.
