Every Year, millions of Sharks are captured on long lines and killed solely for their fins. Many times the sharks are brought up alive and their fins are hacked off and they are usually discarded overboard where they eventually bleed out and die a panful and panicked death. The fins are a delicacy in China where they are often incorporated into a traditonal soup. The soup consists of a beef or chicken base since the fin itself is said to have no flavor. In traditional chinese medicine it's thought to have many health benefits which are largely unfounded by modern science.
As apex predators of the ocean, sharks play a pivotal role in the food chain and without them the collapse of our oceans are immanent.
