The water pressure is too great. It doubles with every 33 feet of depth. The maximum depth for conventional Scuba diving is about 40 m (130 ft), technical divers with specialized gas mixtures may work down to 110 m (350 ft). The depth of the deep sea can be as far down as 4,000 m (14,000 ft)
There are 3 main reasons:
Oxygen becomes toxic when compressed.
Other gasses will have side-effects (like nitrogen) when they are breathed at depth.
Others gasses dissolve into a divers blood and when they surface can bubble (like a can of coke, no bubble when closed, when you open it bubble appear because of the relative pressure change). Large bubbles can injure of kill the diver.
Divers Dive in deep waters because the air tank isn't necessary in shallow waters diving in shallow waters would not make access to air. In deep water the water pressure is so strong that the air tank is necessary to keep them for a supply of air. Secondly in deep waters the exciting views such as coral reefs and the different type of fishes and other underwater sights that are studies are ALL located in deep waters. There fore Diving is best done in Deep waters.
Most technical diving is done in deep water (more than the recreational limit of 130 feet) because that is where the work is - oil rigs and such. For recreational divers, there is an allure of going where few other people can go, and the 100-130 foot range is particularly alluring, as very few divers are qualified to go there.
Using standar air, below about 70 metres, the partial pressure of oxygen is so high (about 1.6 bar) that oxygen becomes toxic. This is called oxygen toxicity.
Most recreational diving organisations recommend a maximum depth much less than this. For BSAC the maximum (with training) is 50. I think for some other organisations it is 40m.
If you are using a gas mix with a higher oxygen content such as Nitrox, the maximum depth would be lower (probably about 40-50m) because of the higher partial mix of oxygen.
There is also the problem with nitrogen narcosis where the presence of nitrogen in the breathing gas impacts the divers ability and can give the effects of euphoria for example.
A thermocline is the boundry layer of two different temperatures of water. The colder water is denser and the warmer water is less dense and so it floats on top of the denser colder water. It is possible to swim from one side of it to the other if the thermocline is shallow enough. Thermoclines can be broken up by large waves mixing the water, so if a thermocline exists, it might be quite deep in Oceans.
I've not heard specifically 1 metre before but obviously the deeper you go the more pressure builds up on the chest that your muscles have to work against to expand the lungs. Eventually, at some depth, your lungs can't do it so you can't breathe!
Scuba gets round this by feeding you pressurised air so the lungs don't have to work so hard; the pressure is balanced inside and out.

Why do scuba divers not get crushed by the weight of water when they are diving?
They do not dive deep enough.
Why are sea turtles good divers?
Sea turtles are good divers because their fins help them dive into the water and help them move all around strong waters.
Who gets decompression sickness?
Scuba divers who surface too quickly after a deep dive are prone to decompression sickness.
How deep can a shark dive?
Recreational divers usually don't go any deeper than 60ft. The recreational dive limit is 130ft.
What type of diving course do you need to dive as deep as 1 mile?
There are not any courses that would train you to dive this deep. Recreational divers are trained at depths up to 130 feet, over 5,000 feet short of your 1 mile mark. Tech divers are trained to dive deeper, however, the pressure of the water at the depth that you asked about would most likely cause severe bodily harm. In diving u shuld be comservative. If i can do or see what i can do or see at 15 metres, why go to 30?
Is used to divers the earth?
Divers dive in the sea/water, not earth.
What do divers dive on?
Diving boards
What do divers jump of when they dive?
the board
How do you use dive in a sentence?
To use it in that form, you could use it as a command. For instance, Dive into the water. To use it in another way, you would have to change the verb tense to "dove" or "diving" or something else like that.
Why do people that want to go deep underwater need a submarine or dive bell?
People need a submarine or dive bell to protect themselves from the immense pressure experienced at deep underwater levels. Submarines and dive bells are designed to withstand high pressures and provide a controlled environment for divers to safely explore these depths without risking injury or death.
Where can one purchase dive knives?
Dive knives can be purchased from a number of websites. Examples include Knife Depot, Scuba, Leisure Pro, Divers Supply, Divers Direct and Divers Warehouse.
Why isn't it a good idea for divers travelling by air straight after a deep dive?
So they dont get the bends and the co2 levels in the body have time to equalize.
