What is blue carbon?

Question

Accepted Answer

Blue carbon is the term for carbon captured by the world's ocean and coastal ecosystems. Hence, option (a) is the correct answer.Sea grasses, mangroves, and salt marshes along our coast capture and hold carbon, acting as something called a carbon sink. These coastal systems, though much smaller in size than the planet's forests, sequester this carbon at a much faster rate, and can continue to do so for millions of years.
