April 22

On this day - 22nd April  1970 - The first Earth Day

Earth day is celebrated on 22nd of April to support environmental protection. Now Earth Day is organized by the Earth Day Network and 193 nations participate. In 1969 John McConnell proposed a day to honour Earth and the concept of peace. However the proposed date March 21 did not stick. It was celebrated in 1970 but a month later a separate Earth Day was started by US senator Gaylord Nelson. The event for 22nd of April focused on the United States of America but one of the original coordinators of the 1970 event turned the event international in 1990. In the 1990 celebration 141 nations participated. There are several groups that celebrates Earth Week that takes the Earth Day message over en entire week instead of a single day.
