“Most sharks are far too small to be vicious killers of men and women, and many sharks live in the deep sea where no humans swim,” points out Dr. Samuel Gruber, professor of marine biology at the University of Miami. “Soda machines killed more people last year than sharks did.” Furthermore, many of these attacks on humans are thought to be cases of mistaken identity or of territorial protection.
Over the last several decades, however, humans have killed a tremendous number of sharks—millions and millions. The result is a that a number of shark species may be approaching biological extinction. Sharks are an immensely valuable and largely unexplored resource, and their loss would be calamitous for many reasons.
