“water covers 75 percent of earth. 97 percent of water on earth is salt water. only 3 percent of water is available as fresh water, but most of this water is locked up in solid glaciers and polar ice caps.” based on this information, which is the best approximation of the amount of water on the planet that is available for animals to drink?

Only about 1%

Explanation:

According to the given condition, the earth is comprised of nearly 75% of water and only 25% of land.

Out of this total amount of water on earth, the water in the oceans and seas makes up 97% of it that are saline and not good for drinking purpose. The remaining 3% of water includes the fresh water such as the glaciers and ice caps on earth, groundwater and others.

Out of this total fresh water, only about 1% of water is available for drinking, which covers significantly very less amount of water on the entire earth.
