Fishing. Shipping. Tourism. The ocean is a mighty economic engine that brings jobs and prosperity to all of us. And this includes tens of millions of the world’s most vulnerable people, who rely directly on the sea to make a living and to improve their lives.
The Ocean is Earth’s life support system. It produces 50% of the planet’s oxygen, meaning that every other breath you take comes from the sea. It’s also a major part of the “water cycle,” which gives us the rain we need to survive. It’s simple but true: Without the ocean, we wouldn’t exist.
More than 1 billion people depend on seafood as their main protein source. And with global demand for food expected to nearly double by 2050, that number is only going to grow. To feed a hungry world, we’ll need to keep our oceans full of fish.
Carbon dioxide and other atmospheric gases trap heat — just enough to keep Earth hospitable to life. But the oceans play a role in our climate, too. They store the vast majority of the carbon on Earth, including much of the extra carbon that people generate by burning fossil fuels and clearing forests. Without the ocean, Earth would be a sauna.
