On the surface, it might seem like an ocean without sharks would be a more enjoyable place. But, these predators play a very important role in the ocean ecosystem and they need our protection just like many other ocean dwelling creatures.
Sharks have been at the top of the food chain for hundreds of millions of years, but today their populations are in danger because of human activities, such as overfishing and finning (this is when people catch sharks, remove the fins, and dump the carcass overboard).

Watch “Shark Conservation: Safeguarding the Future of Our Ocean” to hear about all of the benefits sharks provide and why they deserve our protection.
