  • Earth Day (officially  International Mother Earth Day ) is a day celebrated in many countries on April 22.

    Its promoter, US Senator Gaylord Nelson, established this day to create a common awareness of the problems of overpopulation, the production of pollution, the conservation of biodiversity and other environmental concerns to protect the Earth.

    It is a day to pay tribute to our planet and recognize the Earth as our home and our mother, as different cultures have expressed throughout history, demonstrating the interdependence between its many ecosystems and the living beings that inhabit it.


    In 1968, Morton Hilbert and the US Public Health Service, organized the Human Ecology Symposium, a conference is held by those named above for an environmental assembly or conference for students to hear scientists speak about the effects of environmental deterioration on human health. This was the first antecedent to Earth Day.

    For the next two years, Hilbert and his students worked to plan the first Earth Day. Other efforts emerged such as the Survival Project, one of the first environmental awareness educational events, which was held in Northwestern University on January 23, 1970. This was the first of several events held on college campuses across the United States. Likewise, Ralph Nader began to speak about the importance of ecology in 1970.

    The first demonstration took place on April 22, 1970, promoted by senator and environmental activist Gaylord Nelson, for the creation of an environmental agency. Two thousand universities, ten thousand schools (primary and secondary) and hundreds of communities participated in this call.

    Social pressure had its achievements and the United States government created the Environmental Protection Agency and a series of laws aimed at protecting the environment.

    In 1972 the first international conference on the environment was held. The Stockholm Earth Summit whose objective was to sensitize world leaders to the magnitude of environmental problems.
