Cause a Sea Change: Save Sharks

Sharks play a vital role in the health of our ocean, but in some parts of the world, many shark species are in decline. By contrast, many shark species in U.S. waters are doing well thanks to the efforts of NOAA and fishermen. Learn about the conservation success in the U.S. and why sharks are in trouble elsewhere—and what you can do to help!


Are you afraid of sharks? Half of Americans are afraid of sharks! Half of Americans are terrified of sharks! Even though, compared to shark encounters... in the United States you’re 3 times more likely to be struck by lightning, 39 times more likely to be injured or crushed by a vending machine, 250 times more likely to be involved in a fireworks accident. By contrast, sharks cause 5 fatalities per year on average worldwide. Really? Really!

What’s even scarier? An ocean without sharks While many shark species are doing well in U.S. waters... Many shark species in other parts of the world are in decline due to overfishing.

Why should we care? We need sharks! Why? Sharks keep prey populations in check and remove sick and weak animals In turn, sharks help maintain biodiversity, keeping our ocean healthy ... the same ocean that produces the seafood we eat and half the oxygen we breathe.

Here’s the good news... Together we can help sharks right now. NOAA is already doing something. Thanks to strict controls on shark fishing and the cooperation of U.S. fishermen... Shark populations in the U.S. are on the rebound. In fact, only one shark species managed by NOAA Fisheries is listed as endangered: the scalloped hammerhead shark.

Globally, “shark finning” receives a lot of attention. It’s the practice of removing shark fins for shark fin soup... and dumping the body alive at sea. But shark finning has been banned in the U.S. since 2000. It remains only a small part of the global problem. Overfishing is the larger problem. In many countries, sharks are being fished faster than their populations can recover. But in the U.S., NOAA and fishermen are making a difference. And we are sharing this roadmap to success with the rest of the world.

But there’s more to do. How can you help? Choose U.S. produced seafood. You can be confident that it’s sustainable. Report shark sightings in the “Ocean Alert” app to help scientists track sharks. Share this video with your friends. Because it’s time to cause a sea change
