Here you go bozos. My research/work at the Colorado school of mines is in the realm

Nice presentation. I'm a Mines graduate. There wasn't anything like that going on when I was there - only mining/mineral related subjects.

I believe the point is that there is no NEW water. For example, when it rains, this is water that's been recycled.

This is not true.  Combustion and respiration are both ways that new water molecules are made from hydrogen and oxygen.  Ever see water vapor from your breath in the cold or from a tailpipe on a cold day?

So not the same molecules of water just the hydrogen and oxygen being put back into solution?

I was wondering if they R/O it (from the Times article above): "In Scottsdale, that process involves ozone infusion, microfiltration and reverse osmosis, in which water is forced across a membrane to remove dissolved minerals and other impurities. The water is then zapped with ultraviolet light. Together, these measures remove “darn near everything,” Mr. Biesemeyer said."

I'd brew with it. Probably better quality water than what comes through my tap.  Call it "Yellow River IPA" xD

No, those are instances of chemical reactions where the hydrogen and oxygen from separate molecules combine to form H2O. This is still negligible in quantity overall compared to the molecules that move through the water cycle chemically unchanged, though.

"Combustion and respiration are both ways that new water molecules are made from hydrogen and oxygen."

If this is true, based on the world's population, we should now have more water than, for example, in the 1960s.

That would be true, if humans were the only organisms on the planet.

Agreed but consider how many times each water molecule has passed through the water cycle AND other processes over the length of time that water has existed on Earth.  That's a lot of opportunities for a given water molecule not be be in existence when the dinosaurs were around.  Probably should do the math on this to see just how long, on average, a given water molecule has been around.

But, we're blamed for everything, even things we didn't do or haven't caused. World population has increased, we're daily bombarded with warning about 1 species or another being extinct, hence, the human population has increased and therefore, based on the assertion in a prior post, we should have more water.

If you are correct, it's not likely that we'd detect it anyway as living things comprise only .26% of the world's water anyway.  https://www.usgs.gov/special-topics/water-science-school/science/where-earths-water

The basic process of combustion and cellular respiration is:

(Carbon-Hydrogen Fuel) + O2 → CO2 + H2O + heat/light

But the process of photosynthesis is basically the reverse:

CO2 + H2O + light → (Carbon-Hydrogen Fuel) + O2

So water is constantly being made and unmade.

Yes, recycled.
