Earth Day is a day designed to inspire awareness and appreciation for the Earth's environment. It was founded by U.S. Senator Gaylord Nelson as an environmental teach-in in 1970 and is celebrated in many countries every year. Earth Day is celebrated in spring in the Northern Hemisphere and autumn in the Southern Hemisphere. Many communities celebrate Earth Week, an entire week of activities focused on environmental issues.
In the United States, Earth Day is celebrated each year on April 22. The United Nations celebrates Earth Day each year on the spring equinox, which is often 20 March. This is a tradition which was founded by peace activist John McConnell in 1969. The United Nations first celebrated Earth Day on the spring equinox in 1971. This was also the first time ever that the United Nations celebrated Earth Day. The first Earth Day on the spring equinox was also in 1970.
Earth Day is similar to World Environment Day.
Earth Week, April 16-22, originated in Philadelphia in 1970. It was created by a committee of students (mostly from University of Pennsylvania), professionals, leaders of grass roots organizations and businessmen concerned about the environment and inspired by Senator Gaylord Nelson’s call for a national environmental teach-in. The Earth Week Committee of Philadelphia concluded that devoting only one day to the environment would not provide enough time and space to paint a comprehensive picture of the environmental issues confronting mankind.
Many cities now extend the observance of Earth Day events to an entire week, usually starting on April 16 and ending on Earth Day, April 22.These events are designed to encourage environmentally-aware behaviors, such as recycling, using energy efficiently, and reducing or reusing disposable items.
