Earth Day is an annual event held on April 22nd. Around the world, various events are held to demonstrate their support for environmental protection. Commemorated for the first time in 1970, Earth Day now includes events in more than 193 countries, which are now globally coordinated by the Earth Day Network.
On Earth Day 2016, the Paris Framework Agreement was signed by the United States, China, and other 120 countries.

In 1969 at a UNESCO conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to be held on March 21, 1970, the first day of spring in the northern hemisphere. This day of Equipoise of Nature was later sanctioned in a proclamation written by McConnell and signed by the Secretary-General U Thant at the United Nations. A month later, a separate Earth Day was founded by U.S. Senator Gaylord Nelson as a teaching environment for the first time held on April 22, 1970. Later, Nelson was awarded the Presidential Medal of Freedom Award in recognition of his work. While this April 22nd Earth Day focused on the United States, an organization launched by Denis Hayes, who was the original national Coordinator in 1970, took him internationally in 1990 and organized events in 141 nations.
