Despite their infamous reputation, great white sharks play a vital role in maintaining healthy ocean ecosystems. As apex predators, they help to regulate the populations of other species, and their presence can indicate a diverse and healthy marine environment.

However, overfishing and other human activities have threatened great white shark populations in many areas, and efforts are being made to protect and conserve these important animals.
