Question: What Is Earth Day?
Earth Day is the day designated for fostering appreciation of the earth's environment and awareness of the issues that threaten it. Actually, Earth Day is one of two days, depending on when you choose to observe it. Some people celebrate Earth Day on the first day of Spring, which is the vernal equinox that occurs on or around March 21st. In 1970, U.S. Senator Gaylord Nelson proposed a bill designating April 22 as a national day to celebrate the earth. Since that time, Earth Day has been officially observed in April. At present, Earth Day is observed in 175 countries, and coordinated by the nonprofit Earth Day Network
. The passage of the Clean Air Act, the Clean Water Act, and the Endangered Species Act are considered to be products associated with the 1970 Earth Day.
