H2O

H2O, known as water, is a component which is VERY important. Many people need it, because all living things use it as a beverage. If you don’t drink water for 100 hours, game over, you’re dead. If not, there is a guarantee for throat problems and skin irritation. This is needed especially when climbing mountains, because of atmospheric pressure.
