What % of Earth’s water is available for
US to drink & agriculture (farms)? <1%!!!!!

<1%
freshwater,

for us.
It’s LESS than 1% because of
Pollution…

Hard water has too much Ca & Mg!

Let’s break down Earth’s
precious 3% freshwater

4. Is there more
freshwater in rivers or

AIR?
 Our atmosphere is over a mile thick and very humid
in some places.
 Rivers are thin hairline crevasses on Earth’s 30%
crust where water flows very quickly from
mountains out to salty sea!
