The Antarctic Icecap is the largest supply of fresh water,representing nearly 2%of the world’s total of fresh and salt water. As can be seen from the table below, the amount of water in our atmosphere is over 10 times as much as the water in all the rivers taken together. The fresh water actually available for human use in lakes and rivers and the accessible ground water amount to only about one-third of 1%of the world’s total water supply.
