1) Shark finning involves cutting the fins off live sharks and throwing their bodies back into the ocean, where they die a slow death. It is done to supply the demand for shark fin soup, especially in Asian cultures.
2) Laws against shark finning exist in many places but are poorly enforced, and sharks continue to be harvested at unsustainable rates.
3) If shark finning continues unabated, it could drive many shark species extinct and have devastating effects on the marine ecosystem.
