What if we invent remote controlled robots, and worked towards technological advancement so we can come up with alternate solutions.
Also figuring out ways to recycle the old metal bits from old electronics (seriously, there are a ton of old and/or broken electronics in the world, it’d take effort but we can get stuff out of them), and probably figuring out a way to get stuff from space rocks.
If there isn’t a safe/ethical way, we’ll invent one, capitalism deems it cheaper to waste human lives in such pursuits rather than pursuing the research that would allow us to move past it.
We’ll also have time to do things like explore space which may allow us resources so that no human ever has to do without.
http://electronicrecyclers.com/2014/03/retrieving-what-s-precious-business-of-mining-minerals-from-recycled-electronics I mean honestly we need to stop wasting as much crap, there’d be enough if we stopped being so nonsensical in our resource usage, which is a thing we can do. We can drop our old computer off at the old computer depot, and we can build electronics for greater upgradeability and less bullshit planned obsolescence (which there is a ton of).
I don’t think we’ve got to give up anything but our chains and getting a new phone every two years and not recycling. Instead they’ll just manufacture the best possible phone technology allows in the first place, like the iphone 1 had a space for the camera it didn’t have because they could already put one in, and make it easy to upgrade as tech improves. We’ll have to give up shoes that fall apart after one days walking and go straight to a land fill only to be replaced with similar shit, everyone will have plenty of nice well made things instead. We’ll have to give up using brute force instead of ingenuity. We’ll have to give up shitty appliances that break too fast.
We have nothing to lose, which doesn’t mean that the revolution will be easy, bloodless, or that the first few years while we work out the bugs might be rough, but we can do this.
We’re human, we’re marvelous, our capacity for invention is endless.
Also gold can be extracted from sea water.
We also need to work on agriculture as right now what we do is causing massive long term desertification/environmental devastation because of what plowing does to fungal networks that distribute water between plants, but I think that just means we need to come up with better methods of agriculture.
And we won’t get on to fixing any of this until capitalism ends
