And where does it come from? Can it be made in a lab?

Ok. So earth isn't depleting it's reservoirs of water, but yes the potable one. Where does it go? To the sea? Why is the desert getting bigger? When amazonian forest is chopped, where does all the water it keeps goes? Why doesn't the sea get higher because of that? Why can we only make small amounts of water in a lab?

Water is a compound made of two hydrogen atoms and one oxygen atom, it can be made in a lab, but not in huge amounts, The water on earth came when hydrogen combined with oxygen during the Big Bang (formation of our solar system) later it condensed on earth and filled the huge ditches. they say it is finishing because it is drying out from some part in the world and then precipitating at other. Some of the water vapour in the sky also gets dissociated due to lightning. As you should know nothing can be created or destroyed but transformed from one state to another.

It´s not water that is finishing, it´s the clean available water that we need to survive that´s finishing. The rivers we used to drink from are getting polluted, mostly untreated wastes. Rainfall patterns are changing with global warming, so many countries will experience drought. The same amount of water stays on earth, but it might be polluted or unavailable for human consumption.

yes, we can make water in the lab--even our bodies make water...
but the thing about making water is that we use up hydrogen, oxygen, and energy in the process.
when they say we're running out of water, they mean to say we're running out of potable water--you know, for drinking and watering plants and such. desalination and decontamination is expensive...and for some odd reason, people would rather do other things with their money--
"water, water everywhere--but not a drop to drink"

If someone says the water is depleting, it's a figure of speech. The "standing" water (rivers, lakes, oceans, puddles, yadda yadda...) are becoming smaller.
I hope that's what you meant...

Who says water is "finishing"? What the hell does that even mean?
