get a oxy tank .
Unless you have gills, you are going to need access to oxygen. There is the traditional snorkeling mask, a Scuba tank, or more recently, a new breathing apparatus that doesn't use tanks or tubes.
"An Israeli Inventor has developed a breathing apparatus that will allow breathing underwater without the assistance of compressed air tanks. This new invention will use the relatively small amounts of air that already exist in water to supply oxygen to both scuba divers and submarines. The invention has already captured the interest of most major diving manufacturers as well as the Israeli Navy."

I will give you as much as i know. Humans came from water, far before our current time. You can say we were fish or lived on land and hunted and such underwater, or you can say humans were once mermaids. { Tell me what you think about our weird ability to shrink our pupils underwater, webbing between toes and fingers, and some thing of how our lungs adapt also but i cant remember what it does...It kind of crosses on of those out.} Going underwater as much as possible could cause the body to adapt to it more and maybe then could we go back to the crazy old days of being of the water. I would recommenced starting in a pool then working into the ocean. Who knows what will happen, maybe your body will change, maybe you will waste a large amount of your life. But your lungs WILL change and that is always good :D
well you need an oxygen tank first of all . and you cant survive under water without any oxygen so your best luck is to hold your breath as long as you can.
Because there's like a gillion gallons of water on ya moron.
They use up the oxygen stored in their lungs.
its goes down
It adapts because of its tail it has the ability to swim adn its gills for underwater breathing!!
All living things adapt through the process of evolution.
Thear are 385 pressure points in the human body.
A deep sea vessel. Examples: Alivin and Jason.
Pressure differentials are a cause of structural movement. Since the human body's internal pressure is basically that of atmospheric pressure, the human body experiences no change in structure. When the human body is exposed to vacuum pressure such as in space, the human bodies pressure would exert a force greater than that of the vacuum resulting in the human body to expand...(and explode ). When submerged beneath the ocean at great depths, the human body's internal pressure would not be enough to "push" against the force of the water and would implode...
The pressure underwater. On objects the pressure is 1ATM for every 10 meters underwater. human body feel 2atm in 10meter, but the real pressure on the body 1 atm, but due to our lounges the body suffers 2atm.
i seriously don't know
the fluid pressure 10 ft under water is
On average, a person can hear sounds underwater up to a distance of about 60 meters (200 feet). This distance may vary depending on water conditions, such as temperature, pressure, and clarity.
the air pressure will increase
Fish adapt to the pressure.
It increases
Monkeys cannot survive underwater, they'd need gills like fish. Since they have lungs they could only survive underwater for a short period of time.
by being cold blooded by having second eyelids and by being able to breath underwater
Without proper equipment no human can breathe underwater anywhere.
