What is ‘blue carbon’?

[6-5-2022] Microsoft Rewards Bing Homepage Quiz Question: What is ‘blue carbon’?

The given options are:

  • Carbon emitted by airplanes
  • Carbon offsets purchased by liberals
  • Carbon captured by oceans

Correct Answer: Carbon captured by oceans

Info: The term ‘blue carbon’ refers to carbon that is captured by the world’s oceans and coastal ecosystems. Just as forests on land remove climate-changing carbon dioxide from the atmosphere, the oceans’ algae, sea grasses, mangroves, and salt marshes capture and hold carbon dioxide, acting as a giant carbon sink. Some scientists believe that because oceans cover 70% of the planet, blue carbon has the potential to remove far more carbon than terrestrial forests.
