The Ocean's Most Important Predators Being Killed...But Just for the Fins

Overfishing is an issue commonly tied to species of fish such as bluefin tuna and orange roughy, but it also heavily affects sharks. Tens of millions of sharks are caught each year by fishermen solely for their fins, and once their fins have been removed their bodies are thrown back into the ocean. The fins are then used in Shark Fin Soup, a common dish in many Asian countries. Sharks are at the top of the food chain, which means their reproduction rate is slow, and without as many sharks, lower food chain species overpopulate, and the ecosystem is severely disrupted. In order for the ocean to maintain a stable environment, shark finning must come to an end.

In a few restaurants in London, investigators have caught chefs passing off bluefin tuna as other non-endangered species of tuna.
