1. It helps us breathe
Phytoplankton – tiny plant-like organisms that live in the sea – are responsible for at least 50% of the oxygen on Earth.
2. It helps regulate the climate
The ocean absorbs huge amounts of heat from the sun. “More than 90% of the warming that has happened on Earth over the past 50 years has occurred in the ocean,” according to the US National Oceanic and Atmospheric Administration.
3. It’s an important source of food
Fish is on the menu for billions of people around the world every day. It accounts for almost 16% of all animal protein consumed globally. Of course, there’s more to seafood than fish, crustacea and other edible creatures. A range of algae and sea plants are also commonly used in cooking.
4. Its biodiversity is incredible
It’s not just a source of food. The ocean is also home to an abundance of life. While estimates on the number of species that live in the sea exist, no one knows with absolute certainty what that number is.
