From the Science Channel
THE EARTH is a CLOSED system of environment.
All the water is recycled.
the ONLY way the Earth can get NEW/MORE water is ONLY if an iceball type comet hits us and the ice melts and is added into the system.
OTHERWISE
over the course of millions of years the water goes from rain to salt water to evaporated, to ground water etc etc and the best estimate is that water completely recycles over about a 10 million year period of time.
SO
the next time you have been out sweating that precious water from your system and you take that HUGE gulp of cold WONDERFUL liquid refreshment you need to sustain your life... just remember that there is a HUGELY great possiblity you are drinking what was previously dinosaur pee.
and that is one to grow on
