St. Croix Environmental Association presents the Biodiversity Film Fest: “Learning to Sea.” This underwater experience compares animal behaviors in two seas, the Red Sea and the Caribbean Sea, separated by over 7,000 miles. The filmmaker, director/producer Ziggy Livnat, shares his cross-global experiences and shows the correlation of the marine inhabitants in this international, award-winning film. He will be on hand to lead a discussion after the film. The film will be shown at 8 p.m. on Thursday, April 22, at the UVI Theatre Room 401.
