i know that there is a obvious answer to this question, but i need a better, more scientific explanation on why bacteria do not affect the pH of water like they would to say milk (bacteria break down milk particles which makes the pH more acidic).

Obviously, the body needs a certain amount of oxygen to function. When mountain climbers ascend a mountain, they can have a real tough time with the lack of oxygen. At sea level, we get plenty of oxygen. Why, when we descend into the depths, do we need still more exygen? We aren't burning more calories. I read something once about the breathing reflex being triggered by CO2 buildup rather than lack of oxygen. Does this play into this?
