Shark fin soup is a delicacy in China, but it’s starting to look like they’re having to fish far afield to supply their hunger.

For the first time, DNA tools have successfully pinpointed the geographic origin of shark fins sold dried in markets to satisfy the demand for shark fin soup, a Chinese delicacy.

Twenty-one percent of the Hong Kong market fins were found to have originated in waters off of coastlines of the United States, Belize, Panama and Brazil in places where the shark has been categorized as endangered by the International Union for the Conservation of Nature.

When the appetite for a local delicacy forces you to hunt an endangered species all over the world, it’s no longer a local delicacy, but an international problem. That’s a problem not only China faces. Especially when it comes to seafood, the world’s appetites are threatening to just plain eat the things we love to death.
