Q79. What is blue carbon?
a) Carbon captured by oceans and coastal ecosystems
b) Carbon sequestered in forest biomass and agricultural soils
c) Carbon contained in petroleum and natural gas
d) Carbon present in the atmosphere
Answer: (a)
- Blue carbon is the term for carbon captured by the world’s ocean and coastal ecosystems. Our oceans and coasts provide a natural way of reducing the impact of greenhouse gases on our atmosphere, through sequestration. Seagrasses, mangroves, and salt marshes along our coast “capture and hold” carbon, acting as something called a carbon sink. The ability of these vegetated ecosystems to remove carbon dioxide (CO2) from the atmosphere makes them significant net carbon sinks, and they are now being recognized for their role in mitigating climate change.
