Every idea has the potential to make an impact on the oceans, no matter how big or small it is. In the crystal clear waters of Marettimo, a protected Mediterranean island off the coast of Sicily, we meet free diver and underwater explorer Daniel Bichsel, who shows us a responsible way to examine the deep blue. Daniel’s “Wild Place” has been a unique paradise of colorful coral and abundant sea life. But this paradise is under threat, so the environmentalist and educator recruits ambassadors to preserve the underwater world. Drive-In Screening • April 16
