Because we do not have a limitless supply of fresh (usable) water and our 6-9 billion population along with animals and plants will finish all that water off quite quick
The total amount of Earths total water supply that is usable fresh water is less then two percent. The rest is salt water or pond water.
Since the water that melts is classified as "fresh". the polar ice represents about 50% of the world supply of fresh water. Overall the polar ice is about 2% of all water.
People are major pollutors of Earths fresh water supply.
"The Antarctic Icecap is the largest supply of fresh water, representing nearly 2% of the world's total of fresh and salt water." Source: http://www.infoplease.com/ipa/A0004674.html

1% of water is usable in this case .Since only 3% of water is usable as fresh water, 2% is unavailable in frozen form leaving approximately 1% of the earth's water usable.
All fresh water isn't usable because 97 percent of the water is found in the oceans as salt water. About two percent of the earth's water is stored in glaciers , ice caps, and snowy mountain ranges. That leaves only 1 percent of fresh water that is readily available to us for our daily water supply needs

The amount of Earth's water that is usable as a freshwater resources can vary. There is a very large percentage of freshwater available, but much of it is unobtainable.
North America is the country that has the most usable fresh water. The United States and Canada almost tie for their water resources due to glacier lakes and rivers.
No, Groundwater makes up about twenty percent of the world's fresh water supply, which is roughly equal to the total amount of freshwater stored in the snow and ice pack, including the north and south poles.
Yes. Though the air you're breathing might not exactly be 'fresh,' you do get a fresh supply with every inhalation.
