Shark Stewards

Sharks have swam the oceans for over 400 million years, helping to shape and maintain the balance of ocean ecosystems. Sharks have survived the five great extinction events, including the last which caused the dinosaurs to go extinct.  For all this time, sharks were the top predators in the ocean.

Until Now.

Today, many species are threatened with extinction within our lifetime.  Overfishing and shark finning is killing tens of millions of sharks per year at an alarmingly unsustainable rate.

Fortunately, global attitudes are rapidly shifting in favor of sharks.  We are at the forefront of the glocal movment to protect sharks, ban the shark fin trade, stop illegal shark finning and establish shark sanctuaries.

There is lot to do to support shark populations, and Shark Stewards is here to help.  We provide the tools for activists to take action and stop shark finnning and ban the shark fin trade.


Shark Stewards is a project of The Earth Island Institute, an environmentalist think tank founded by David Brower and a 501c3 non-profit.  Launched as Sea Stewards in 2006 by award-winning film conservationist and marine biologist David McGuire, Shark Stewards is dedicated to conserving our oceans through the protection of sharks.
