April 22, 2020 is the
50th Anniversary of Earth Day

The National (and now International) Earth Day was first held April 22, 1970.

Wikipedia best summarizes:
"Earth Day is an annual event celebrated around the world on April 22 to demonstrate support for environmental protection. First celebrated in 1970, it now includes events coordinated globally by the Earth Day Network[1] in more than 193 countries.[2] ...

Earth Day was founded by United States Senator Gaylord Nelson (from Wisconsin) as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom award in recognition of his work.[6] ... an organization launched by Denis Hayes, who was the original national coordinator in 1970, took (Earth Day) international in 1990 and organized events in 141 nations.[7][8]"

Senator Nelson:
"The ultimate test of a man's conscience may be his willingness to sacrifice something today for future generations whose words of thanks will not be heard."

Earth Day Mobile Bay has a related anniversary: 2020 is the 30th Earth Day Mobile Bay and will be celebrated Saturday, April 18 2020.
