Ninety-seven percent of the world's water is salty or otherwise undrinkable.
3% is fresh, but 2% is frozen in the polar ice caps. That leaves just 1% for
consumption by all living creatures, including plants and animals!

A dairy cow needs to drink four gallons of water to produce one gallon of milk.

Water is the only substance found on earth naturally in three forms: solid (ice),
liquid (water), and gas (water vapor).
