The correct option is A. Blue carbon refers to the carbon captured and stored by the world’s coastal and marine ecosystems.
– These ecosystems include tidal marshes, mangroves, and seagrasses.
– They are highly effective at sequestering carbon, often storing it in their soils and biomass for millennia.
– Protecting and restoring blue carbon ecosystems is considered a crucial strategy for climate change mitigation.
Carbon stored in forests and terrestrial vegetation is often referred to as green carbon. Fossil carbon is the carbon contained in fossil fuels like coal, oil, and natural gas. Atmospheric carbon is primarily in the form of carbon dioxide (CO2) in the atmosphere.
