Hi.I love swimming and underwater activities, but I just randomly was wondering : Why can't people breath underwater?
Try SCUBA diving!! I love swimming underwater too and love scuba diving. It's the most incredible sport I've ever done. You get to see all the great stuff in the ocean. Try it!
When you go through a certification course you can learn all about the human physiology and diving. We have other differences from marine mammals that prevent us from diving like they do even if we could hold our breath longer.
Is there any safety precaution must i caution of when i swim at the beach?
no gills...not enough air content in water !

You know, I would like to breath underwater, too.
Unfortunately human body doesn't not permit us to breath underwater. The problem is that we've got lungs, not gills.
Water is made up of Oxygen and Hydrogen, so...why can't we breath it?
Fish can "breathe" the dissolved oxygen out of the water using the gills.
Humans cannot breathe underwater because lungs do not have enough surface area to absorb enough oxygen from water, and the lining in lungs is adapted to handle air rather than water.
Moreover, the amount of oxygen that dissolves in water is far too low to sustain human life.
However, there have been experiments with humans breathing other liquids, like fluorocarbons. Fluorocarbons can dissolve enough oxygen and lungs can draw the oxygen out.
