Earth Day? That is, April 22nd every year is a festival specially set up for world environmental protection, aiming at raising people's awareness of existing environmental problems, mobilizing people to participate in the environmental protection movement, and improving the overall environment of the earth through a green and low-carbon life.

Earth Day was initiated by Gaylord Nelson and dennis hayes in 1970. This activity also played a positive role in promoting the convening of the first United Nations conference on human environment in 1972, and made mankind fully realize the important connotation of "only one earth".

History of Earth Day

1970 "Earth Day" on April 22nd was the first large-scale mass environmental protection activity in human history. As the beginning of modern human environmental protection activities, this movement catalyzed the development of modern human environmental protection movement, promoted the legislative process of environmental protection in western countries, and directly gave birth to 1972 the first United Nations conference on human environment.

Earth Day aims to arouse people's awareness of caring for the earth and protecting their homes, and promote the coordinated development of resource exploitation and environmental protection. In the publicity activities of "Earth Day" on April 22 every year in China, the theme of the activities is determined according to the situation of that year.

In 2008, the theme of "Earth Day" determined by China is the same as the propaganda slogan of "International Year of Earth" in China, that is, "Be kind to the earth-start with the little things around you".
