Water is one of the most important substances on earth and all living things depend on water to survive. In humans, water makes up 60% of adult bodies and without water humans cannot survive longer than a few days depending on activity and environmental conditions. Because water is such a vital resource we need to understand where it comes from and how to make sure we will have enough drinkable water in the future.
