Why are wetlands so important?
Wetlands are among the most productive ecosystems on Earth. They filter drinking water for billions of people, store more carbon per hectare than tropical rainforests, protect coastlines from storms, and support over 40% of the world's species. Despite this, 87% of the world's wetlands have been lost since 1700.
What is blue carbon and why does it matter for climate?
Blue carbon is the carbon stored by coastal ecosystems — mainly mangroves, seagrasses, and salt marshes. Mangroves alone store between 1,000 and 2,500 tonnes of carbon per hectare. When these ecosystems are destroyed, that carbon is rapidly released into the atmosphere.
How do mangroves protect communities from storms?
A 100-metre wide mangrove belt can reduce wave height by 50% and significantly attenuate storm surge. Each hectare of mangrove provides an estimated $65,000 per year in storm protection.
What can I actually do to help protect wetlands?
Support organisations that fund restoration (Wetlands International, Global Mangrove Alliance); reduce meat and dairy consumption; choose sustainably sourced seafood; and reduce household water use to ease aquifer pressure.
