Scott:Despite the fear and fanfare, there is no reliable scientific evidence, empirical or anecdotal, showing that shark tour activity is hazardous or causes harm to sharks, to people taking shark tours, to people engaged in other water activities in deep-water, to people in or around the reefs, or to people on the beaches.
Shark tours are conducted in deep-water, miles from shore. Sharks encountered in deep-water are deep-water species, not near-shore or reef sharks. Deep-water sharks do not follow boats back to shore. They stay in the deep-water because that is their natural habitat.
