 . . . Or it could be that after being fed by humans worldwide for years
they have come to associate people with food and, just like bears, while
most don't attack, some get the lust and do. I don't know and I doubt that
at this point anyone can say for sure that feeding does or doesn't lead to
increased attacks, but that certainly IS a big change in the relationship
between humans and sharks.

Along with global warming and the positions of the constellations . . . .
