Microsoft Rewards Bing Homepage Quiz: What is ‘blue carbon’?
A Carbon emitted by airplanes
B Carbon offsets purchased by liberals
C Carbon captured by oceans
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.
The correct answer to this quiz is Carbon captured by oceans.
