Why is the Ocean so important to Humans?

Oceans generate half the air we breathe and contain 97 percent of the water on earth. Oceans are home to many types of animals that we eat. ¨¨Living oceans absorb carbon dioxide from the atmosphere and reduce climate change impacts. ¨¨ Oceans absorb 50 times more carbon dioxide than our atmosphere. That is incredible.  Oceans are filled with life and we need to protect them.  Our food chain is also connected to the ocean.
