Why is shark finning cruel?
Without sharks, the health and productivity of our oceans—and dependent livelihoods and economies—are at risk. Because of the high commercial value of shark fins and the relatively low value of shark meat, fishermen often take only the fins and leave the rest of the body behind—an extremely cruel and wasteful practice.

Sharks are fished for their meat, liver oil, cartilage and valuable fins, which are hacked off, often from live sharks, to be used in shark fin soup, an ancient and prized delicacy in East Asia.

So yes, brutally chopping sharks’ fins off while they’re still alive is illegal. But importing and exporting fins is still allowed, even while some populations decline.

What animals Cannot feel pain?
