Today we join the world in celebrating the 50th anniversary of Earth Day. Since 1970, WCS has been marking the day by advocating for the conservation of wildlife and wild places. The first year included the Bronx Zoo’s first “graveyard” of extinct animals, lectures and film screenings for Bronx Zoo visitors, and an all-day teach-in at the New York Aquarium. Shown here is the Bronx Zoo Children’s Zoo in 1970. For more on this history, check this link.
