Imagine discovering an island that is so pristine and remote, far removed from any mainland that it’s difficult to locate even by experienced navigators. Upon diving into these waters you discover teams of fish swimming in vast networks of diverse marine organisms. After observing this habitat for multiple days and on various islands around Pitcairn, you noticed one important detail is missing from these waters, sharks are missing.
How is this possible in a clean remote ocean front? Where have all the sharks gone and what caused this to happen? How can this be a balanced ecosystem without sharks to patrol the waters?
Pitcairn and the islands that surround this area are considered one of the most pure waters of the Pacific. With this in mind, Dr. Enric Sala, a marine ecologist, explains this observation and how it is hurting this ecological community.
