Sea rewilding
Sea rewilding (also known as marine rewilding) is an area of environmental conservation activity which focuses on rewilding, restoring ocean life and returning seas to a more natural state. Healthy seas sequester carbon. Globally only 13 per cent of ocean waters are still wild.[2] Rewilding marine and coastal ecosystems offer potential ways to mitigate climate change.[3][4] There are a range of organisations and projects internationally tackling this area of climate challenge work.[5] Sea rewilding projects are currently less common than those focusing on rewilding land, and seas are under increasing stress from 'The Blue Economy' – commercial activities which further stress the marine environment.[6]
Seagrass
Seagrass meadows store carbon dioxide. More than 90 per cent of the UK's historic seagrass meadows have been lost.[7][8] Restoring meadows could offset carbon emissions and provide habitat for numerous fish and shellfish species.[9] Research into seagrass, which covers about one per cent of the sea floor suggests that it may be delivering 15–18 per cent of carbon storage in the ocean.[10][11] Meadows have been declining since the 1930s and are being lost at an alarming rate.[12] Due to their scarcity they have been designated a UK habitat of principal importance.[13] In the United States a project at Chesapeake Bay is considered a success.[14]
Native oysters
Oysters clean waters, recycle nutrients and help to protect against coastal erosion. Oyster stocks have declined by 95 per cent in Europe due to over-harvesting, habitat loss, pollution and disease.[15] Restoring historic oyster beds improves water quality.[16]
Kelp forests
Kelp forests are important habitats which have been lost over time in coastal waters.[17][18] Kelp forests provide habitat for fish, protect coastlines from erosion and trap carbon dioxide from the ocean. They grow fast and absorb large amounts of carbon.[19] Restoring kelp forests is a strategy to address climate change and enrich ocean livestock.[20]
Marine protected areas
Environmental groups, such as Rewilding Chile, are campaigning to create new marine protected areas.[21]
Carbon capture
Rewilding the sea has been described as "the new way to capture carbon".[22]
