Michael, new houses get plumbed with plastic. I’m not saying that’s a good thing, plastic pollution is another major problem, but it does cut down the demand for copper. And as Lapsed Agnostic has pointed out, a vast quantity of copper can be salvaged as plumbing systems get replaced.
Given the comments on piping I indulged my curiosity about the advantages and disadvantages of copper and plastic plumbing.

I’ve looked at a few links this one is a good overall summary.
I guess if copper is needed more for other things then plastic piping is a good substitute.For you Michael, Radical electric motor runs without metal coils. Still in a lab and with all sorts of downsides but maybe someday we’ll have alternatives to copper (or metal) conductors.
For you Fat John DARPA sets new records for sending power wirelessly.
Very inefficient but that’s where we’re at.ET, the company you just linked to is right next to my nearest railway station! Come to Chelmsford for good, clear technical advice; we’re a load of geeks here.
Though we can’t get apostrophe’s right :-/
Lol.Clark, I was gonna apologise to you that I didn’t have a specific link for you. I’m a kind of (drunk right now) geek, I might fit in.
ET, your link is quite specific enough. I had noticed your geekery, and I congratulate you on it.
