Earth Day is an annual event, celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network,and celebrated in more than 193 countries each year.
Earth Day is celebrated every year on the 22nd of April. In 1970, a senator from Wisconsin, USA, Gaylord Nelson first conceived of this day. The senator was worried about the rate of industrialisation and the careless attitude of everyone towards our environment. It was envisaged to promote the idea of ecology, to encourage respect for life on Earth, and highlight growing concerns about different kinds of pollution. Over 20 million Americans participated in events to mark the first Earth Day and it turned out to be so contagious that today, over a billion people from all over the globe celebrate Earth Day.
