Each year, Earth Day marks the anniversary of the birth of the modern environmental movement in 1970. On April 22, 1970, 20 million Americans took to the streets, parks, and auditoriums to demonstrate for a healthy, sustainable environment in massive coast-to-coast rallies. The idea came from Senator Gaylord Nelson who wanted to promote a national teach-in on the environment at colleges and universities between Spring Break and Final Exams.
International Mother Earth Day
International Mother Earth Day was established in 2009 as a recognition that "the Earth and its ecosystems are our home" and that "it is necessary to promote harmony with nature and the Earth." The term Mother Earth is used because it "reflects the interdependence that exists among human beings, other living species and the planet we all inhabit".
