How Whales Change Climate

 First, Whales eat fish and krill, then they poo, it has iron and nitrogen. Then, the plant plankton grows which sucks the carbon dioxide out of the air. Then it goes and remains at the bottom of the ocean for thousands of years. This helps climate change by reducing the amount of carbon dioxide out of the atmosphere. If this does not happen, more carbon dioxide will get into the atmosphere and this will cause more global warming.
