By that logic, also the CO2 footprint of manufacturing and transporting the fuel for an equivalent ICE vehicle, which is always conveniently left out of such calculations.
And also the footprint of building more generation stations (big) or building “renewable energy” generation (even bigger), which also conveniently gets left out.
The greenest choice most of us can make is an old, used car with reasonable emissions and that’s fuel efficient. Like a 15 year old Civic or Corolla. Or do what a colleague of mine did - he revived a first generation Prius, flashed newer software onto it, and salvaged a battery pack from a newer, wrecked Prius.
As pointed out by other nearby comments, that is not the greenest choice (which is to not drive), nor even the second greenest choice (which is to replace your ICE with a refurbished Prius like your colleague), or even the third greenest choice (which is to buy a new EV), but only barely beats out the worst non-green choices (buying a new ICE) and then only if you pay to make sure the car emissions controls and engine aren't becoming rusty and inefficient. Here's an article explaining: https://www.topgear.com/car-news/electric/mythbusting-world-...
There are also the caveats you mentioned that the analysis does assume that an EV is actually the greener choice, which is itself a function of a lot of other choices being made green also, such as whether it was constructed and powered with the most environmentally favorable choices of mining and manufacturing, most of which isn't really in the consumers direct control.
The actual scientist doing the calculations in proper LCAs do include this and production of the fuel is a notable chunk of the CO2 running cost of an ICE car (about 25%).
Relevant phrases are "well-to-tank" and "tank-to-wheel" which combine to give "well-to-wheel" numbers.
GP started with the premise "we don't need one printed in the 21st century".
A more generous reading of that argument might be "we don't need one authored in the 21st century", not that textbooks would never need reprinting and last forever through two dozen owners
I'd have a problem believing that too, because I see that my oldest child's math textbook (for the last year before starting university) is better than my own was. Not very much, but enough to give me the impression that the textbook authors are paying attention to how their work is used and improving it (maybe by <0.1%) in each edition.
D'oh! Thanks. I had indeed interpreted the person they were replying to as talking about authorship rather than printing …despite them saying “printed”
I suspect "MRI-strength electromagnet" falls into a different budget category than "medical grade and certified imaging system", including but not limited to "MRI removed from hospital and junked because it's no longer maintained / useful / accurate enough". They are pretty resourceful
I don't mean to post a low-effort response, but Betteridge's law of headlines seems to apply here.
If the answer to the question posed in the headline was "yes" they would have stated it as such.
Instead it seems that "don't change things despite the world changing, decreased availability of resources, and increased completion for said scarce resources" is the main thrust of the post?

I'm no expert, but I'd assume "cleared for emergency evacuation in space" means "if the alternative is imminent, certain death - this option is better".
My understanding (correct me if I'm wrong) is that the tariffs are based on the source location of the battery components. Assembly doesn't matter unless you start mining lithium in NAFTA? That's why it's gonna hit some ebikes and the like.
I've known more than a few ex-religious of varying types who in young adulthood have to find an explanation for why:
- they are not at all who the faiths they were raised by said they should be
- they know there's not actually anything wrong with themselves (or others like them), despite what their faith taught them
Squaring these two deeply personal realizations is challenging. People take many paths. Your interaction is an outlier, but by no means the most extreme I've encountered.
