I got the water propaganda too, second hand form.

Teacher said: "When I was a kid my teacher told me that we could run out of water, and we said how could you run out of water, you turn on the tap and there's tons of it. Now we're not so sure."

It's now over 20 years since then, and likely around 50 since you and my teacher were originally sold the line.

You can still turn on the tap and get tons of water. Water levels in the great lakes are higher then they've been in decades. Probably more beachfront property got damaged by the fresh drinkable water than rising sea levels.
