What is ‘blue carbon’? I thought carbon was black.
“Blue carbon” is the carbon that is stored naturally by marine and coastal ecosystems, hence the name. Three types of coastal ecosystems — mangroves, seagrasses and tidal marshes — store half the “blue” carbon buried beneath the ocean floor.
What’s so important about blue carbon?
It’s important because the release of carbon into the atmosphere is a major driver of climate change, and because blue carbon ecosystems hold a LOT of carbon — a given area of mangrove forest, for example, can store up to 10 times as much carbon as the same area of land-based forest.
