This.
If you deliberately attract predators to an area by providing easy prey, then you are asking for trouble.
That's why there are signs all over North America and Canada saying "DON'T FEED THE BEARS" (and we on the coast of the North East have signs saying "Do't feed the seagulls').
Feeding doesn't only attract the predators to the area, but it accustoms them to seeing humans as a food source. They become bold (NOT tame!0 and lose their natural instinct to avoid humans. (Very few wild animals deliberately target humans if they have another food source, and that includes most species of shark.)
When human beings both destroy an animal's natural food source, and then provide it with an alternative which leaves ourselves open to being predated, we can hardly complain when a wild animal takes advantage of it.
Sharks are repulsive to most of us (as are alligators and crocodiles) but they are hugely important in the marine ecosystem , and they are rapidly nearing extinction - and it is due to us. We have destroyed their food sources, polluted their waters, and hunted them for sport and occasionally for food, as in the Chinese shark's fin market which is one of the cruellest trades you can imagine, and heaven knows there's a lot of competition for a cruelty award when it comes to the way people treat animals!
If we continue as we are, an animal which is so perfectly adapted to its environment that is has remained essentially unchanged for many millions of years will be gone within the lifetime of our children.
That's nothing to be proud of.
