Oceans sustain life. They cover 71% of our planet’s surface, make up 95% of all the space available to life, produce 70% of our oxygen, absorb heat and re-distribute it around the world, and dominate the world's weather systems. From the freezing Polar Regions to the warm waters of the tropics, they are home to iconic marine species such as sharks, turtles, whales and more. Oceans are also critical for people as a source of food, culture, and history. They support 1 billion people who rely on fish as an important part of their diet and more than 520 million livelihoods who rely on fishing and fishing related activities for income and food.
WWF’s ocean work focuses on healthy and resilient marine ecosystems that support abundant biodiversity, sustainable livelihoods, and thriving economies.
