'The problem with fresh water is that it's unevenly distributed around the world. Some places are rich in the resource and they'll never run out, whereas in other places the resource is very limited and that is where the problems can arise.'

People say we'll never run out of fresh water...but I've always wondered..
What number humans body's on earth would take up the available fresh surface water? (Not any potential currently unused water sources, e.g. ; desalinization, deep ground water, etc)
Considering the human body is compromised of 60% (~42 liters/11 gallons) or even more water, and the current population of 7-8 billion people already uses up.
I've always wondered because of all the articles discussing this most fail to mention the water inside of humans and only refer to their daily water usage, cattle and crops.
You can't just say we'll never run out water because everything has its limits, but understandibly water may not be the limit that breaks first in this equation.
On what grounds can a freaking well be illegal? People don't dig 40.000 wells for fun or for others to declare them illegal. What are they to dig instead if wells are illegal?!
@DIngbat donedon there's no such thing as overfarming. There's only underwelling. Just capture more rain or create a lake.
Once we develop effective nuclear fusion, we will be able to desalinate as much sea water as desired and pump it to all the currently marginal farmland.
This is why more funding needs to go into nuclear fusion rather than unreliable wind and solar.
Just after Nestle bottle it all.
I think Anson is related to Anderson Cooper
Primary water is the answer to unlimited water supply for the world. This is something that has been proven scientifically and it’s quite feasible as a solution to the freshwater problem. Primary water is stored beneath the earth and is 2 to 3 times greater than the amount of water in our oceans. This water which is created under pressure finds its way to the surface eventually and can also be drilled for easily. Just do a search for primary water on RUclips or the web.
I watched the video 3 times. I learned zilch. Cool clickbait climate alarmist title gets answered with: high demand in arid or in comparison insufficientely irrigated areas will be the areas where we ought to expect deficiencies.
Does anyone else hear more somewhere?
Yes. I posted in comments.

Not necessary.
