By "we", are you referring to your locality? There are numerous places, in and out of the U.S., where available usable water is insufficient for human wants, even without any environmental policy.
yes. i realize that many areas of the world do not have enough water. 50 years ago in bermuda, i observed roof catchment systems.
LOL ...WHY I love PriusChat. You can listen to 'discussions' about sea level rise AND water scarcity. The wet stuff covers about 71 percent of our little planet, and yet it's quite rare in these parts- making up only about 0.05 percent of our planet's mass......but up to 60-percent of out bodies. ...so we're really INTO water. No salt, please. Inasmuch as you can believe poly-science these days, some say that about a quarter of our liquid water has been lost over the years through various processes. And yet the oceans are DEEP. (Trust me!) If the Earth was a smooth spheroid instead of it's irregular squished down at the top and undulated self - then water would cover the entire planet at a depth of over a mile and a half. ...briefly. The earth....like many of us is a little thicker in the middle because it is (we are) spinning at a rate of a little less than 15 degrees per hour. This doesn't sound (or feel) very impressive, but you'd need a Concorde to keep up with it in the middle.....and they stopped making those. In other words......if you stopped the world to get off, the water probably wouldn't hang around very long either. You'd also have to cool off the inside to keep the crusty parts from crinkling and that would "probably" effect the condensation on the skin. Anyway.... Like many things, there's plenty of water to go around.....at least for now. We're simply not very good at water management. Followers of the great philosopher Walter Elias Disney say that: "All drains lead to the ocean." So..... My beloved home state has a rainwater collection statement that's pretty simple: "There are no restrictions or regulations on rainwater harvesting and it is highly encouraged by the state...." In like manner, my adopted home state considers rainwater harvesting to be a private property RIGHT and "allows" private citizens to actually collect rain water permit-free......beeeeeecause...... "All drains lead to the ocean." Me? I hedge my bets. I have 2 rain barrels..........and a privacy fence.
They have grey water reuse in Florida too - something else that's not really a "thing' in other places although greywater regs in the Keys are principally written about boats.
"WHY I love PriusChat. You can listen to 'discussions' about sea level rise AND water scarcity. " (ETC)SS I also like Prius Chat for the wonderful discussions and diversity of topics and opinions. Years ago before moving to a small city to be closer to my job we lived on a rural farm. Our water source was a well. It was filled through an underground aquifer and supplemented by runoff. I could start a whole thread on problems you run into with well water access,dependability and water quality. The area had depressed property values because of no municipal water lines. We had water all around -but healthy drinkable water for 365 days a year through summer droughts rainy/muddy season etc = real trouble. Municipal city water is a real blessing and convenience we often take for granted.
As linked from post #95, the same is true through most of this country. Except where they don't: Endorheic basin The largest U.S. example is the Great Basin, covering most of Nevada, half of Utah, and a good chunk of Oregon. But elsewhere, very significant portions of Earth's land mass have a similar situation, where drains don't lead to any ocean. And many of these areas do have locally sparse supplies of human-usable water:
Lots of houses on the little island where we used to live had them as well. Probably true for many, if not most, islands. We got by without needing to catch rainwater because we were blessed with a deep and usually reliable well.
me too. with a well, it's cheaper to drink bottled water and hope it's safe, than have well watertested every year and wonder if the missed anything
