Though terrestrial forests typically get most of the attention, they are not the only ecosystems that possess a natural ability to fight climate change. There are three coastal ecosystems that are also highly effective at sequestering carbon dioxide: mangroves, seagrass, and salt marshes. The carbon that is captured and stored by these coastal ecosystems is known as “blue carbon.” Pound for pound, these blue carbon ecosystems can actually store up to 10 times more carbon than tropical rainforests!
