10 Things you Probably Never Knew About Water

by Natalie Haber


1)    One’s body is made up of about 70 percent water. However, at birth it accounts for 80 percent of a newborns body.


2)    Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.


3)    Somewhere between 70 and 75 percent of the earth’s surface is covered with water.


4)    The total amount of water on the earth is about 326 million cubic miles of water.


5)    Of all of the water on the earth, humans can use only about three tenths of a percent of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.


6)    The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water.


7)    By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.


8)    The weight a person loses directly after intense physical activity is weight from water, not fat.


9)    A healthy person can drink about three gallons (48 cups) of water per day.


10) The earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same water that existed on the earth millions of years ago is still present today.
