Watch Healthy Seas: Mission to Santorini (2019) : Full Movie Online Free Over 640,000 tons of fishing gear are left or abandoned in the seas and oceans each year. It is a major environmental problem that requires immediate attention. The Healthy Seas initiative works with volunteer divers to remove the plastic nets from the seas and makes sure they are regenerated to produce a sustainable new yarn. The film follows the divers on World Oceans Day during a mission in Santorini, Greece as they recover half a ton of ghost nets. During an unprecedented underwater live-stream, Pierre-Yves Cousteau described the mission to inspire the protection of the World’s Seas and Oceans.
