Sharks might not be a substantial chance to us, however we’re to them. Humans are accountable for drastic declines in shark populations. Overfishing is the most important chance. A hundred million sharks are killed every year, mainly to deliver a call for a luxurious Chinese dish known as shark fin soup. Some fisheries permit the capture of entire sharks, like some other fish, whilst others have outright banned shark fishing. 

Sometimes fishermen reduce the fins off stay sharks and sell off the animals, finless, lower back into the ocean, wherein they`ll drown or bleed out. This exercise is known as shark finning, and it’s performed to shop area at the boat (the fins are the maximum treasured a part of a shark) and to keep away from surpassing fishing quotas.
