Guess what? Not everyone has clean tap water to drink in their homes. Surprising to you? We have small towns here in MO that the water is not potable.
Clean water is the first thing to go. It is what as known as a limiting factor in our ecosystem.
Not sure why you are being snarky in a thread where we are discussing our opinion of the future.
Ah well. . .I probably should just let this one go, but, one more try!
I was pointing out that on balance, many more millions of people have clean water today than had it 50 years ago when technology was limited.
And yes, people in MO have clean water. . .they DO have access to it. They can stock up on clean milk jugs and go fill up the back of the car with clean water from a relative/neighbor/3rd party tap once a month the way some of my relatives have done on occasion. It may not come out of their taps, but they can get it.
Think about that. They CAN get clean water. For most of human existence, large swaths of humans could NOT always reliably get water that was clean! It might have looked pretty and crystalline and taste achingly good, but it might have harbored parasites and microbes and all sorts of nasty critters and the humans who were alive at the time would never, ever know until they became ill.
Let's even add insult to injury; much of the time, those same humans wouldn't even know it was the water that had caused the illness!
Now, through one means or another, we can all get clean water!
Of course, when parts of MA were under a boil notice, people panicked and griped and complained - and all they had to do was boil their water! The fact that the water came in from reservoirs in the middle of the state, through a marvelously engineered system, and was driven through pipes into their houses - something that hasn't existed for almost all of the existence of the human species, just didn't occur to them. I guess it's just a lack of appreciation for history?

(And yes, I've had to boil water before. It's just something you do. A pain sometimes, but ya' know, sometimes it's necessary.)
I don't think we're anywhere near headed the direction of Logan's Run; quite the opposite in fact. (Although I have been reliably informed that I used to watch the TV show and had quite the crush on Gregory Harrison!) I mean, think about it. Even 30 years ago, there were many more people in the world without clean water or access to it than there are now, and heck, most of those people didn't know how to curb the diaherra that impure water can bring!
Even in this country, 30 years ago, in rural communities, there were far fewer water co-ops than there are today and many (I was one of these) rural dwellers relied on well water. Now, those same people don't have to worry about getting a well dug, about it filling in, about testing the water, about impurities in the water. Now they hook onto the community water.
Before that, 50, 60, 70 years ago, those same families didn't even have any sort of water in the house except what was hand pumped in, because they didn't have electricity to pump the water into the house!
So yeah, things are definitely moving in the right direction pretty quickly. Some parts of our water infrastructure are crumbling, but the fact that we're all alarmed by this indicates that we recognize the importance of that infrastructure and can remedy the situation. Maybe not as fast as some would like, but we can do it.
I think we should remember and be appreciative of all the work and engineering and time and effort that those who came before us have put into the marvels of our modern world and how many humans now have those marvels.
