On April 22, the Triangle will celebrate Earth Day’s 39th anniversary. Founder and former Sen. Gaylord Nelson of Wisconsin wrote that the inaugural Earth Day in 1970 “worked because of the spontaneous response at the grassroots level. … That was the remarkable thing about Earth Day. It organized itself.” It’s up to us to continue the tradition.
