In the last couple of weeks, calls for the debunking of the "kill sharks and we'll all die 'cos the oxygen will go" myth have surfaced again and over at The Best Shark Dive in the World, Mike has now had his say here.
Mike's post is a more detailed variation on the theme laid out last week by Rick and Patric and is probably the best of the three purely owing to the detail. This blog isn't my weighing in because that would be pointless as I would have nothing to add of any value that they have left out and because I am not an environmental biologist, this is just me pointing you, my faithful reader, to these articles and imploring you to read them.
I am not perfect, not by any stretch (hard to believe, I know,) and I did once buy into the idea that sharks help regulate oxygen etc because I didn't really have a reason not to, I had seen it on the shark conservation "big bang" that was "Sharkwater" and I thought, "hey, that's an interesting concept, I'd not thought of it like that before," and because the dude telling me was a biologist, I didn't feel it was my place to second guess it.
I am not a biologist, nor do I feel the need to claim to be one to validate what I am saying, I'm just a dude that likes sharks a lot and so with that in mind, when I don't know something, or I at least start to question something, I ask people who do know what they're talking about and whose opinions I trust. Having done that with regards to this particular subject I now understand a lot more and see that yes, it is complete nonsense.
I certainly don't want you to feel this is criticism of you if you, like I did, espouse this myth, it isn't, nor am I telling you you have to believe everything written in the linked blogs, all I'm saying, is don't be afraid to question things and at least now you have the chance to research the subject further, if we want to start "educating" others, then we need to educate ourselves first. Secondly, I don't think it is our place to appoint ourselves in any position to "educate" anyone, we should instead concentrate on inspiring others.
