Yao Ming has been a leading activist in trying to ban shark fin soup, but the campaign needs more voices if it's going to be successful. The latest effort to raise awareness is a documentary film called Extinction Soup, which is being released Monday as part of the World Ocean's Day celebration. The film goes into detail about how the mass slaughter of sharks threatens the balance of life in the ocean's ecosystem. Those disruptions have a ripple effect on humans, which is part of the message: If you don't want to do it for the sharks, do it for yourself.

Check out the trailer, followed by a PSA:

The film is available on VOD outlets such as iTunes, and it is scheduled to be televised on the Fusion Network.
