Who would have thought this thread would have touched a nerve as sesitive as "Guns on Board", "Cat vs. Mono", "____ Anchors are the Best!" threads! (Apparently not Chief Engineer
, the OP, or he would not have put it up - or would he?)
There are some very strong opinions expressed here on both sides of the argument, some well reasoned and some just emotional. Hopefully without adding any more fuel
to the fire, I'll chime in with my thoughts.
General widespread anihilation of all or part of a species is almost always unjustified, except perhaps for smallpox virus, HIV, Lionfish, and other species that are just too nasty to be useful. The obvious exception here being eliminating cockroaches from boats. Nearly every living being plays a role in the world ecology. We humans are far from understanding the complexities of all those roles so we should NOT use wholesale extermination as a means to shape the environment
to our liking.
Given Swagman's detailed and repeated explanations of the geography of the waters off Perth, I tend to agree with WA's selected removal
of sharks that have developed an affinity for attacking humans, similar to National Park Service
practice of killing bears that attack humans. Implicit in this agreement is their ability to identify correctly the offending shark.
Are there any Marine
Biologists knowledgable of shark behaviour or otherwise qualified shark experts on CF who would care to confirm or deny the size of shark's brains, their propensity for learning
behavior, or their like or dislike for the taste of human flesh? Perhaps your contribution would cool some of the heated emotions we have seen in this thread. Please specify your qualifications if you do post here.
As a parting thought, I wonder whether Steven Spielberg regrets having made the movie
, "Jaws". Probably not with all the $$$ he made on it.
However the author of the novel, "Peter Benchley has mentioned that if he had known about the actual behavior of sharks, he would have never written the book." [Quoted from imdb.com]
