The Earths surface is covered by 80% water. 97% is saltwater and 3% is fresh water. Of this 3%, 68.7% of the available drinkable water is locked up in ice frozen near the north and south poles making it unaccessable to most of the world. See the related link for more information.
cuz we humans are very complex so we can only drink clean water but since there is polution we can no longer drink water from a stream or lakes or rivers and stuff like that. you could drink ocean water but that would taste horrible. :D
Some people in certain geographical areas haven't the means to access fresh water supplies or to treat the water for human consumption.
It is frozen into polar ice caps and glaciers.
Because the other 97% is pure saltwater and its too salty to even drink it like normal water.
Most of the earth's fresh water is in the polar ice caps.
because it is coverd by ice
because its in the polar ice caps
fasf
1 % of the 3%. The fresh water is trapped in the ice caps and the air. The 1% of the 3% of the fresh water we use are rivers, streams lakes, and ground water.
because its in the polar ice caps
0% we all should die
no
This depends on what you mean with 'human use'. But it is estimated that 2.75 percent of all water on Earth is fresh water (which I believe is what you mean). Most of that however (2.05) is frozen in glaciers. A further 0.68 percent is ground water, with only 0.011 percent being surface water (in lakes and rivers).
only about 3 % is fresh water and less than 1 percent of that is available the rest is frozen in glaciers etc
Less than 1%Explanation: Just 2.5% of the planet's water is fresh. Less than 1% is readily available for human consumption because some of the fresh water is stored in the form of ice bergs.actually, it is 4.04% of the world's water is fresh water
Roughly 1% of the world's freshwater is readily available for human consumption in the form of rivers, lakes, and groundwater. The majority of Earth's freshwater is locked up in glaciers and ice caps, making it inaccessible for immediate use.
cause most of it is the sky
cause most of it is the sky
Less than one precent of the earths water/
Because most of the water is salt water
As it is similar in structure to human hearts and they are readily available whereas most humans are buried with their hearts.
Type your answer here... 1 percent water 2 percent ice
Insulin from pigs is cheaper and more readily available than insulin from humans.

for a human. the human supply water usage is 3%. ONLY 3 PERCENT IS DRINKABLE TO HUMANS
