Earth Day is an annual event held on April 22nd. Around the world, several 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. This signature fulfilled a fundamental requirement for the entry into force of the climate Protection Treaty of the Historical Project, approved by consensus of the 195 nations present at the United Nations Conference on Climate change in Paris in 2015.
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.
Countless communities celebrate Earth Week, a whole week of activities focused on the environmental problems facing the world. In 2017, the March for science took place on Earth Day (April 22, 2017) and was followed by the climatic mobilization of the people (April 29, 2017).
