I'm not saying that the loss of someones life and the grief suffered as a result is not tragic but I can't help feel this whole shark debate is an entire @#$&!
I think drum lines and culling sharks is just a 'there, there' pat on the back to placate some, even if you were to catch and kill many sharks over three metres whose to say any one of them would have been one of the few destine to kill.
Everyone knows there are sharks in the ocean, we choose to enter the ocean, surfing, spearfishing, boating, it's inherently dangerous (duh!).
Warning systems can't be 100%, someone has to sight the shark first, the information needs to be confirmed and relayed and there's always going to be the same idiots out there who prank call 000 crying shark.
Cull the sharks? If a person gets killed by a bus crossing the road do we get rid of all the buses, if a boat sinks and the crew drown do we get rid of all the boats or perhaps just the particular type of boat they were in, where's the logic in the cull (kill and get rid it of because we're all afraid) solution?, where does it end? Tragedies usually happen as a result of a persons chosen actions and bar small children and the mentally delusional we're all aware of possible consequences, good or bad of our actions, it's just that in most cases we choose to push the bad to the back of our minds and go out and do what we want to do anyway.
Funny but in Darwin they have their large population of crocodiles that were once hunted with numbers being reduced to an unsustainable level. The hunting ended and the crocodiles became protected, most people in Darwin choose to just stay out of the water, when occasionally a person is taken a huge culling debate over crocodiles is not resumed. It's simply assumed a tragic, unfortunate loss and understood that the person had chosen to enter the crocodiles territory. Maybe that's what needs to happen a massive cull of sharks to the brink of extinction, then we'll protect them and learn to respect and accept our place in their environment.
We should either just stay out of the ocean or accept that if we choose to enter an environment where there are sharks that we may be taken or just cull them all.
