World Earth Day🌎 

World Earth Day is celebrated on April 22 every year. Gaylord Nelson first introduced the concept of Earth Day in the year 1970. The oil explosion in Santa Barbara in 1969 severely harmed the aquatic and terrestrial ecology. He decided to honour a day dedicated to nature after this tragedy. It was widely celebrated in the US, but it started being observed around the whole world later on. More than 193 countries are now celebrating this day, and people involve in environmental preservation activities on this day. It is celebrated in schools and colleges by performing dramas and other activities with the theme of ecological preservation.
