No. It's a never ending cycle. The water that's on Earth is the same water that the dinosaurs drank.
However, we can run out of fresh water. Nearly all the Earth's water is in the oceans; when we use water from lakes and rivers we contaminate it so that it can't be used again until it evaporates and re-falls as rain (or we purify it somehow, which takes a lot of energy).
Because water is recycled in the water cycle, the water supply is to some extent limitless. However, in many parts of the world "usable" water is limited. Most, if not all of the time this is due to the ground not holding water as well as in area's of the world that "usable" water is plentiful. In other words there is plenty of water on Earth for everyone, but getting enough to everyone in a usable form is a problem that man has not solved.
Yes, there's scads of water, we're practically swimming in the stuff. The problem is that it's not always where we need it, and far too much of it is contaminated with salt.
No, the Earth will never run of water, but all the water could get dirty if not enough people try to clean it.
It doesnt run out of water because this whole earth is surrounded by water and when the water drains, it rains to full up again so therefore we should never run out of water

Dow Live Earth Run for Water - 2010 - TV was released on: USA: 23 April 2010
Actually, the Earth will run out of water. In around 1 or 2 billion years from now, the sun will be hot enough to boil all of the Earth's oceans and all life on the Earth will be ceased during that time. The Earth will be scorched and discolored, and will become a lifeless planet.
water is a source of living it is very important source of living now if you ask about how does water run earth then it is simple we know that earth is consisted of innumerable vegetation and living source the only way by which existence of such living is possible is through water thus we can say that by this reason water is the only source running human being and thus we say that water is source that runs the earth.

Earth's water is continuously recycled through evaporation and precipitation, so there is a continuous supply of water for use.
no, water covers 95% of all earth so we wont run out anytime soon.
It ensures that the water on Earth does not run out, for water is a vital need fro living things, especially humans.
because of the water cycle. It reuses water that was here billions of years ago. So really, you could be drinking dinosaur spit.
