Ocean Literacy Principle 4: The Ocean Makes Earth Habitable

Did you know that tiny plants in the global ocean generate at least half of the oxygen that we breathe? Today around 21% of our atmosphere is made up of oxygen — plants, land and sea, sustain this vital atmospheric balance that is critical to supporting the global biodiversity we know and love. This teaching animation is based on The Ocean Literacy Framework, developed by many scientists and educators from the ocean sciences education community. This project was supported by funding from the National Marine Sanctuary Foundation.
