Sharks. It's a Numbers Game.

This month, during the 25th anniversary of Shark Week on the Discovery Channel, people around the world are talking about the awe and beauty of sharks. But there's something quite serious going on with these top predators that people may not know: They are disappearing from our oceans, and fast.

Industrial fishing over the past 60 years has drastically depleted shark populations. As key predators, their decline has risks for the health of entire ocean ecosystems. Now it's time to make sharks count.
