Presentation: Shark Movements and their Impacts on Conservation

Please join us for this presentation from David McGuire, who has a real dedication and passion for sharks.

Sharks have swum 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 part of the Earth Island Institute, a 501c3 non-profit based in the San Francisco Bay area. 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.

Start a Shark Stewards Chapter.
Support Shark Sanctuaries and Shark Fin Trade Bans.
Stop Shark Finning.
