Water has a regulating effect on climate: water vapor in the atmosphere can block 60% of Earth's radiation and protect the Earth from cooling. Oceans and land bodies of water can absorb and store heat in summer to keep the temperature from getting too high, and slowly release heat in winter to keep the temperature from getting too low. Water can be used to generate electricity: hydropower has high efficiency, low electricity generation costs, quick unit start-up and easy adjustment. Water is the main component of the human body: water is the most important substance after oxygen. In the adult body, 60 to 70% of its mass is made up of water.
