Students started an anti-war movement in the country.

To promote the idea across the nation, a team of 52 people was formed, and the 22nd of April was selected as the date to start the environmental movement.

On 22nd April 1970, the first Earth Day was observed when around 20 million Americans took to streets, parks, auditoriums, and other public places to demonstrate support for a sustainable environment and a better Earth.
