A Journey by Blue Marine Foundation

Rainforests of the sea

We use audio to enhance your experience. Coastal ecosystems teeming with marine life.

Mangrove forests, tidal marshes and seagrass meadows make up these underwater forests, known as ‘Blue Carbon Habitats’.

What is ‘Blue Carbon’?

Just like forests on land, these coastal wetlands and marine habitats absorb carbon dioxide and trap it in the soil below for thousands of years. This is important because too much CO2 in our atmosphere traps heat and drives climate change. ‘Blue carbon’ is what we call the carbon captured and locked away by these ocean habitats.

Mangroves connect the land to our ocean

Mangrove forests prevent coastal erosion, store large quantities of carbon and are a perfect nursery for marine life.

Marine life is vital for mitigating climate change. Mangrove forests store more carbon than rainforests, while creating homes for thousands of marine species.
Coastal salt marshes also sequester vast amounts of carbon. They reduce the impact of floods and storms, help control pollution and support entire food webs, from fish to shorebirds.
Seagrass acts as a nursery for some of the world’s largest fisheries and provides food for iconic species like sea turtles.

Here's a fact for you...

Some seagrass meadows can bury carbon 35x faster than the same area of rainforest.

These Ecosystems are under threat.

Blue carbon habitats are threatened by coastal development, unsustainable fishing, climate change, deforestation and pollution.

Their destruction releases stored carbon back into the ocean and atmosphere, speeding up climate change.

We must act now or risk losing more of these valuable ecosystems.

How long can coastal wetland habitats store carbon for?

A haven for marine life

Coral reefs are often found near blue carbon habitats - they support at least a quarter of all marine species on earth.

Coral reefs are under threat

A warming ocean puts coral under stress - as temperatures increase corals become ‘bleached’.

Microscopic algae (zooxanthellae) give coral its vibrant colours. If the water gets too warm the algae are expelled, creating a ‘bleaching’ effect which can starve and kill the coral. This affects whole ecosystems on which people and wildlife depend.


Blue Marine Foundation is working to

Protect our future

In the Maldives, Blue Marine is working to increase the resilience of coral reef ecosystems to climate change. We do this by improving marine protection and promoting sustainable forms of tourism and small scale fishing

Just 100 yards of mangroves can reduce wave height by up to 66%, which helps reduce erosion and flood risk.

That’s about the size of a football pitch!
