Australian think they should "cull" sharks: why not "cull" dumb ass divers?

here is a story about another shark attack in australia, this time a young boy was lost.  Tragic of course.  but why was the boy's dad diving in water known to have sharks?  What precautions did the dad take?  Sharks live in the ocean, duh.  Its not like they crawl up on land and attack us while we sleep.  we go out into their playground, in a black dive suit, dive underwater, act like we are seals or prey, and the sharks attack us.  Its out fault, not the sharks fault.  Sharks play an important role in ocean ecology.  there are plenty of places to dive without fearing shark attack in australia.  and there are ways of diving in shark waters and still be safe, like having spotters, calculating the time of day sharks are active.  Easiest just to avoid shark infested water.

and BTW surfers know there are sharks in the water, surfers paddle far out, in deep water, even in shallow water there can be sharks, when there is a shark spotting surfers feel safer because at least someone SAW the shark.  Sharks are there, we just cant see them.  Sharks wont attack a surfer while surfing, because the surfer doesnt look like prey when surfing the board on a wave.  but when a surfer is paddling, waiting for a wave, they look like a seal.  and you dont necessarily see sharks if they are swimming around you.  the whole dorsal fin thing (da da, da da, the shark soundtrack with the dorsal fin) is a myth.  sharks are invisible usually, they stay under water. you see the dorsal fin only in shallow water.  but surfers love to surf, so sharing the ocean with sharks is part of the challenge of surfing. Like jean paul sartre said:  "No complaining!"  (but i dont think he surfed......)
