The coastal city of Deerfield, Florida made headlines this weekend for hosting the world’s largest underwater cleanup. This year, for the city’s 15th annual cleanup event, 633 divers gathered on the beach to scuba dive and collect more than 1,500 pounds of debris. By the number of divers participating, this cleanup is officially the largest in the world. Divers traveled internationally and from all over the country to participate in the event, and a Guinness Book of World Records officiant was on-site to confirm that the event indeed broke the previous record held by divers in the Red Sea.
