The issue with aviation hydrogen is… well, lots.
Fuel cells are heavy and direct combustion is inefficient and tougher than burning kerosene.
Aircraft typically use the wing structural members as the fuel tank walls. Both cryogenic and pressurised options make that a non-starter.
Lower density means much bigger tanks.
Self-vapourising fuel is a major crash issue.
Round trip efficiency for H2 is still terrible.
Plants may not be particularly efficient per km^2 but arable land isn’t actually that hugely scarce.
Reducing aviation is really the only thing that’s actually going to work.
I believe that would exclude Canada, Aus, and NZ which are pretty firmly considered first world.
Work pants with pockets for built in kneepads.
If you do any kind of maintenance or trades, you’re probably kneeling a lot.
Knee pads make it so much more comfortable but they’re usually annoying and tight, even painful.
Putting them in the trousers makes it a non issue.
Biofuels/ethanol/SAF are much the same; often derived from corn.
In many cases, the oil/gas/electricity used for harvesting, processing, cracking etc. is actually comparable to or exceeds the carbon released by simply drilling for and burning the oil in the first place.

IIRC ‘point blank’ means no need to adjust for bullet drop due to gravity. This is well within that.
Brick does really badly in earthquakes, at least without major reinforcing. ‘Unreinforced masonry’ can be fatal pretty easily.
Brick veneer over timber framing can be a thing.
“Stop getting worse” is a pretty major improvement. And yes, trees work as carbon sequestration.
Most (all?) CCS is not grabbing random carbon from the atmosphere. It’s pulling it out of smokestacks so you can keep burning fuel while claiming it’s green. It is not net negative even if working as intended.
It’s nearly midnight here. Still dumb.
They’ve been deporting those who are there legally too.
With an insufficient workforce, pay rates going up isn’t necessarily enough to get you workers. Moving regions to get a new job isn’t usually cheap or fast.
I don’t know if the previous pay rates were illegally low (the US’s definition of illegally low is itself low), but that doesn’t necessarily mean that they couldn’t & wouldn’t pay ~$20-30/h if there were workers available.
Going from a labour-cheap world to a labour-expensive world also implies that people want to increase mechanisation and automation, and that’s not cheap or fast either.
There were so many plastic miniatures in the game that tooling alone was a crushing financial burden that would cripple the merchandise line commercially before anything else was even produced.
Injection molding NREs are high? Such a well kept secret up to now. I never would have guessed.
AF447 is sometimes blamed on lack of coupled sidesticks amongst other possible deficiencies in aircraft design. Pilot error doesn’t happen in a vacuum.
Certainly not the same situation as the 737, though.
