What role do dolphins have on the oceans ecosystem? Tiffany Schleicher

They play an important role in fighting infectious diseases among fish populations and ensure the reproduction of fisheries resources. It has been proved in many studies that the elimination of top predators in marine systems has negative, cascading effects for the entire ecosystem. By killing dolphins, we are killing the sanitary police of the oceans, which may result in more diseases and diminished fish populations. To kill a dolphin, therefore, means to directly damage sustainable fisheries.

Without dolphins, the species of the ocean could go 2 ways. Fish and any other animals dolphins might eat, will explode rapidly in population. As far as the food chain goes, Sharks and killer whales population would decrease majorly. Completely changing the whole ocean.
