Earth Day is observed to create the greatest environmental movement in the world and to spur revolutionary change for both people and the environment.
It spreads knowledge about measures to keep the environment clean and about pollution.
The idea was developed by Senator Gaylord Nelson and was motivated by the 1960s demonstrations. Since 1965, people have observed Earth Day.
To reach as many students as possible on college campuses, Earth Day was first observed on April 22 as a nationwide teach-in on environmental issues.
The emphasis of Earth Day festivities is on working locally while thinking worldwide. Examples of this include assisting in community gardens, planting trees, and cleaning up water sources.
