@btschumy@mas.to @benlockwood@ecoevo.social @gwentlarry@mastodon.social also, electric heavy machinery is definitely a thing: https://evmagazine.com/top10/top-10-electric-construction-vehicles Electric motors are superior to combustion engines for a lot of applications actually, now that battery tech is available to give them decent operating times. As for concrete, there are a ton of other construction materials if you don't focus solely on dense urban architecture. Do we need 20-storey apartment buildings? Not sure on that one. Don't get me wrong; there *are* a ton of changes necessary to live sustainably, some of which would be uncomfortable, and some modern things (like cheap bananas in temperate regions) might change. But these specific examples are wrong if we're trying to make the case that more technical advances are needed before we'd be able to do so. In any case, we are very much *out of time*. Either we change now, or magnify the climate disaster to unsurvivable proportions. We definitely *don't* have the technology to miraculously survive unbridled CO2 emissions.
