Spearfishing, abalone, and lobster hunters also disagree. Rules like this are as ill-informed as never hold your breath. The rule correct rule is "Never hold your breath, or block your airway, when ascending on Scuba (or surface-supplied)". The rule regarding touching is to use some common sense.
Agree. Common sense. Obviously the posts are discussing animals, as opposed to plants, and as a shell collector I am classified as a hunter I guess, so it's not about that. I have never been a fan of the "Take only pictures (responsably....), leave only bubbles". That seems to mean everything no matter what the situation, and tends to get some divers up on their high horse. Said to me once when someone saw my poke spear for flounders---"Don't kill them, they're my friends". Silly to say if you eat meat at all (considering last summer I got 5). Personally I have no interest in touching or interacting with aquatic animals and don't even like the idea of being around anything that approaches half my size (I know I am unusual in that). I do enjoy seeing a nice fish swim by, or rock crab on the bottom. I don't see a lot of fish here, due to decades of over fishing, so I'm told. I did see a school of TRIGGERFISH 3 years ago here in Nova Scotia.
I think common sense also come into play when considering what you're touching--ie. I doubt I'm doing much if any harm if I grab seaweed, kelp or the like while diving in the North Atlantic (perhaps for a reason, like current, cramps), as opposed to grabbing onto a piece of coral in Aruba just because it's there. As well, there are very few divers at a lot of sites here and often I'm the only one. I know damage done by even one person is a big no-no.
As far as divers being ambassadors of the deep, etc., yes I agree. But as I have often said, I think the ocean has way bigger problems created by those other than our .14%.
This is a very "touchy" (pardon the pun) and popular topic--2-3 more posts since I just relieved myself...
While I think such threads/articles are good, or at least can't hurt, I think we are better served by getting on the band wagon to help clean up the real ocean killing messes. I good example is what they did with the Hudson River since the 70s--People actually swim from beaches there now, as opposed to walking across it to Jersey. I wish I were more dedicated and joined in such causes.
A little off topic, but I must add--
Around 40 years ago my mom told me she used to regularly swim in the Hudson in her youth (1930s-40). Until one time when she literally came face to face with--well, we all remember the Caddyshack pool scene. Since 2003 I have swam and fished there every summer and have yet to see that floating O'Henry Bar.
