Mangrove forests play an important role in the global carbon cycle, particularly within the marine carbon system. Growing along tropical and subtropical coastlines, these salt-tolerant trees are among nature's most efficient "blue carbon" sinks, capturing and burying vast amounts of carbon dioxide that would otherwise warm Earth's atmosphere. Much of this carbon is stored in thick, waterlogged soils, where it can remain locked away for centuries, making mangroves a major contributor to long-term coastal carbon sequestration.
