Sharks are at the top of the food chain in the ocean because they are natural predators that keep the food chain in check. They regulate the amount of smaller fish and organisms living in the ocean by preying on them. As a severe consequence of shark finning, the decrease in the number of sharks directly results in the increase of other organisms and decrease in others causing an imbalance in the food chain. As some organisms in the middle of the food chain increase in numbers, those at the bottom decrease in numbers resulting in the eventual demise of everything in the food chain. Human intervention is causing a restructuring of the ecosystem in the ocean. Sharks control the population and the fewer of them there are each year, the more disrupted the food chain in the ocean becomes.
