Last 21st April we celebrated the Earth Day and our Secondary students gave some advice to Primary students about caring our planet.Earth Day is an annual event, celebrated on April 22, on which events are held worldwide to demonstrate support for environmental protection. It was first celebrated in 1970, and celebrated in more than 192 countries each year.
In 1969 at a UNESCO Conference in San Francisco, the date proposed was March 21, 1970, the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a Proclamation signed by Secretary General U Thant at the United Nations.
