To help overcome the threats facing our oceans, these ocean-loving A-listers are leading the way in marine conservation. Find out which stars are doing their bit to help the environment and save our planet's seas.
As well as being an Ocean Elder, one of a group of influential figures who lend their time and expertise to ocean conservation projects, Richard Branson has also set up Ocean Unite through his company Virgin. The non-profit raises money for environmental charities, funds ocean research projects and hosts a number of events and initiatives to encourage involvement and educate the public about the issues facing the seas - such as dressing up as a mermaid to support World Oceans Day.
Alongside raising money and awareness for ocean conservation, Branson has also taken part in a number of deep-sea dives to help marine researchers learn more about our oceans. Most recently, Branson joined a team of experts in an Aquatica Submarine to submerge 124 meters into the Belize Blue Hole. As well as broadcasting a live stream of their expedition, Branson helped conduct an analysis of the animals and bacteria living in the giant underwater sinkhole.
