Oceans
BACK TO ALL ACTION CATEGORIESOceans support life on Earth in many ways. We can support ocean health by changing our actions wherever we are.
Life started in the ocean, and 97% of the planet’s water is in oceans. Even though oceans cover 71% of the planet, 95% of the oceans have yet to be explored by humans. Oceans regulate our climate, produce half of the oxygen we breathe, create important ecosystem habitats for marine life, and provide food and sustainable livelihoods for millions of humans. Our oceans are currently at risk from climate change (which acidifies ocean water), agricultural runoff, plastic pollution, and overfishing.
