Fish do not perform chemical separation of oxygen from water; instead they use the dissolved air that exists in the water in order to breathe. In the ocean the wind, waves and underwater currents help spread small amounts of air inside the water. Studies have shown that in a depth of 200m below the sea there is still about 1.5% of dissolved air. This might not sound like much but it is enough to allow both small and large fish to breathe comfortably underwater.

well, to me, it just sounded as if we were using the dissolved air that was trapped in the water and not the oxygen from H2O.
and to me, if it were using the dissolved air only, it would take some time to replenish it as well. remember i'm not talking about a mere 1 soul out there with this new breathing apparatus. i'm talkin lots of divers and submarines.
the idea in itself is cool. but you can't deny that x amount of years ago, when aerosol cans were invented, there wasn't 1 person that said...'it's the atmosphere, what will 1 can do to it'...and now? we have managed to fuck the world up.
i'm just bein a bit cautious. i would love to dive and explore but not at the expense of all sealife.
