How Did Earth Day Come To Be?

In 1969, after a massive oil spill in Santa Barbara, California, the then-Senator Gaylord Nelson of Wisconsin was so affected by the wide-scale devastation he saw that he was inspired to raise awareness about the damage pollution can cause. After rallying together activists, researchers, and experts from various political and environmental fields, Nelson held the first Earth Day on April 22, 1970, according to Earth, with an amazing 20 million total supporters across America.

Nelson was able to tap into and give direction to a long-brewing sentiment that the Earth did indeed need help. The high standards for water quality, clean air, and the protection of endangered species that seem commonplace now are all possible because of the awareness the inaugural Earth Day raised. According to Live Science, Nelson's actions resulted in public support for the creation of the Environmental Protection Agency (EPA) and contributed to the passage of the Clean Air Act, the Water Quality Improvement Act, the Endangered Species Act and several other environmental laws.


Why Is Earth Day Held On April 22?

Though some demonstrations were held during the Spring Equinox in the beginning of the environmental awareness movement of the early '70s, April 22 is the official date of Earth Day. But do you ever wonder what the significance of that specific day is?

It turns out that Nelson believed that impassioned college students would be the backbone necessary to bring about the shift in global thinking. According to, he decided that April 22 would be best opportunity to reach out to students on college campuses nationwide.

In addition to conveniently working around academic schedules, it was also a nod to another significant environmental celebration, Arbor Day. The event synonymous with tree-planting and taking pride in performing civic duties for the community was originally held on April 10. In 1855, when Arbor Day was declared a legal holiday, it was changed to April 22 to commemorate the birthday of its founder, J. Sterling Morton, an environmental activist in his own right.


Who Benefits From Earth Day?
