Founded in 1970 as a day of education about environmental issues, Earth Day is now a globally celebrated holiday that is sometimes extended into Earth Week, a full seven days of events focused on green awareness. The brainchild of Senator Gaylord Nelson and inspired by the antiwar protests of the late 1960s, Earth Day was originally aimed at creating a mass environmental movement. It began as a "national teach-in on the environment" and was held on April 22 to maximize the number of students that could be reached on university campuses. By raising public awareness of air and water pollution, Nelson hoped to bring environmental causes into the national spotlight.
Earth Day was first suggested by John McDonnell (from the United States) in 1969 at a UNESCO Conference on the Environment. The United Nations began an Earth Day celebration on the March Equinox and continued this celebration every year since.
In 1968, Morton Hilbert and the U.S. Public Health Service organized the Human Ecology Symposium, an environmental conference for students to hear from scientists about the effects of environmental degradation on human health. This was the beginning of Earth Day. For the next two years, Hilbert and students worked to plan the first Earth Day. In April 1970—along with a federal proclamation from U.S. Senator Nelson—the first Earth Day was held.

According to Nelson, the name "Earth Day" was "an obvious and logical name" suggested by "a number of people" in the fall of 1969, including, he writes, both "a friend of mine who had been in the field of public relations" and "a New York advertising executive," Julian Koenig. Koenig, who had been on Nelson's organizing committee in 1969, has said that the idea came to him by the coincidence of his birthday with the day selected, April 22; "Earth Day" rhyming with "birthday," the connection seemed natural. Other names circulated during preparations—Nelson himself continued to call it the
