Airplanes fly at high altitudes where air pressure is lower than at ground level. This is because the atmosphere is less dense at higher altitudes, which means there are fewer air molecules per unit of volume. To maintain a comfortable and safe environment for passengers and crew, the airplane cabin needs to be pressurized. This involves pumping compressed air into the cabin to maintain a safe level of air pressure, similar to what you would experience at an altitude of around 6,000-8,000 feet (1,828-2,438 meters) above sea level. Without pressurization, passengers and crew could experience health problems such as hypoxia, altitude sickness, and gas expansion. Therefore, pressurization is necessary to ensure a safe and comfortable flight experience.
