Volunteers, fishermen and Greenpeace campaigners during an activity in Dakar, where hundreds of people celebrate World Oceans Day. The event is held on the “Parcours Sportif", one of the most famous beaches of Senegal where people gather every afternoon for jogging and sports. The activists, some wearing fish costumes, demonstrate how they all rely on healthy and beautiful oceans through a choreographed "flash mob" accompanied by music.
