Because the air pressure drops the higher you go. If the cabin wasn't pressurised to ground level - all the passengers (and crew) would eventually suffocate !

What would happen to a passenger if airplanes are not pressurized?
They would suffocate.
What altitude are commercial airplanes pressurized to?
The highest altitude is 8,000 ft. But depending on the aircraft, it is usually pressurized to around 6,500 to 7,000 ft.
When airplanes fly high in the atmosphere why must they be pressurized for the passenger's safety?
the cabin could explode or crack
Why must airplanes be pressurized?
At the high altitudes which airliners fly in, there is less dense. Since air is good for us humans, the cabin is pressurized in order to provide enough air to breathe.
What aircraft can fly in the thermosphere?
Jet or rocket powered, with a pressurized cabin.
Why are airplanes pressurized?
Most air planes are pressurized, because at high altitudes, the air pressure is less than humans can handle, which causes us to black out. Bad vacation when your pilot blacks out at 30,000 feet!
Why do airplanes need to be pressurized?
Airplanes need to be pressurized because the atmospheric pressure, at such a high altitude, acts upon your body. Your body is trying to adjust to maintain equal pressure, causing your ears pop. Because your body cannot maintain equal pressure by itself, the airplane makes up for the rest of the pressure that is needed to equalize the atmospheric pressure.
Why you suppose that airplane windows are smaller than bus windows?
Airplanes are often pressurized. A large window would be excessively difficult and expensive to make it strong enough to not blow out. So they use small windows on airplanes.
Is aircraft carying cargoes pressurized?
Generally yes. Few large commercial airplanes travel under 10,000 feet where you need oxygen or pressurization.
Why are aeroplane cabins pressurized?
Airplanes often fly at great altitudes, of 10 kilometers or more. People would have serious trouble breathing at that altitude.
Why do you not experience a drop in air pressure when you travel via airplanes even though airplanes travel at high altitudes?
It is because an aeroplane's cabin is pressurized, meaning that it is sealed off from the atmosphere. This prevents air escaping and keeps the pressure constant.
What is legal on airplanes?
The question nowadays is "What ISN'T allowed on airplanes?" Items such as aerosol cans; toothpaste; soda cans; and most (if not all) pressurized cans and aren't allowed on airplanes due to the fact people have miss used them as weapons. Then there's the obvious, guns; knives; sharp metal; any other type of weapon (blade.. etc.)
