Sure, it's a closed system. But it's about the volumes that are being consumed and the transfer rates between stages outlined in your image.
Americans use large quantities of water inside their homes. The average family of four can use 400 gallons of water every day, and, on average,
approximately 70 percent of that water is used indoors.
7 billion, divided by 4, multiply by 400 right? Might as well call it 100 gallons a person/day.
If the world would consume at this rate, that's 700,000,000,000 gallons of water a day! You take this away from all the lakes or fresh water sources
at this rate, it will never be returned in a fashion that respects any local ecology.
It's like saying, "A" gives volume of 10v to "B" and then "B" gives it to "C", and "C" then returns it back to "A", creating your closed
model. Then introducing party "D" who wants any value, lets call it 1v, but this time, "D" has to be responsible, because that "1v" can't just
be given to "A". Whatever "D" has, changes the cycles, and doesn't go right back into the system. Which is a terrible thing, because that 1v is
held out, while at the same time "D" takes another "1v" as time progresses, now removing 2v from the system.
It's obviously not that cut and dry, but I think that should make sense lol.
So it's either, start recycling water(achievable), lower consumption rates(achievable, but not preferred), or say "screw it" and consume resulting
in the destruction of the ecology of Earth.
Sure, there's a lot of water, but there's a lot of people and a lot of waste. All of this waste can't just be tossed back into the system, unless
you disregard nature. At these volumes, the disregard of nature could result in our own demise in the end. Simply put I guess.
