  • To elaborate and give a few exmples, LCA data is highly specific to a single production process, and might cover entirely different things.

    There’s a huge difference between “one liter of paint from prepared from pigment and solvent” and “Me driving over to get a house sanded and cleaned, then repainted, per square meter of wall”. But both are LCA’s for painting, but the latter will be much higher.

    It can go the other way too. There are also lots of sub-processes that have negative costs. Putting up a new streetlight has a environmental higher cost than replacing one, because replacing one gives you an old streetlight to recycle. You can’t just create a pile of “streetlight LCA data” and take the average.

    They can even be very time-specific. If I’m sitting on a giant mountain of gravel, I can give you an LCA for your zen garden that’s much lower than last year when I had to import gravel from Norway.

    Looking at chocolate here, they include lots of land-use-change, which is caused by cocoa farmers expanding and turning trees into cocoa farms. But that’s only because they’re expanding. The next harvest won’t have that change.


  • The majority of CO2 from moving food is created by you driving to the supermarket for groceries. It’s not hard to see how when you compare a 15 ton truck moving 30 tons of food, compared to a 2 ton car moving 4 kg of food. That truck can move 1000 times further than a personal car for about the same amount of CO2 per kilo of food.

    This same logic means it’s more efficient to buy tomatoes from a continent away than to drive to the market to buy tomato seeds.



  • Reading what he says about other cultures is very interesting specifically because of that. And on top of that, he’s extremely eloquent.

    It’s a pretty rare glimpse into the mind of a man who was very educated, and wellspoken and who saw everyone who wasn’t white as truly, and regrettably, lesser. And yet despite being so horribly racist, he did feel strong obligation that these poor almost-humans needed help, in his colonizing, appropriating way.

    Its fucking terrible, but there aren’t people like that anymore. There isn’t someone who will go “yeah, all of them [slurs] are dumb fucking shits, but damnit we whites owe it to help em out!”

    And no, ffs, let’s not bring that back. But that doesn’t make it less fascinating.

    Also, we’re very used to the most of the insulting and degrading racism of today, but Kipling had very much a condescending racism that’s pretty rare today. Something like Gunga Din is praising and elevating someone… Because his work as a water carrier is very impressive for someone so inferior.







  • When somebody publishes a bullshit paper that is eventually withdrawn, every subsequent paper citing the fraudulent work can also be withdrawn as being unreliable.

    It depends on how foundational it is, of course. If you could swap it for a dozen other papers, nobody cares. If you’re continuing the work from a retracted paper, you’re fucked (but then, you probably would have noticed some errors pretty soon anyway).

    I have a friend who basically ran a series of experiments based on a paper that was complete bullshit. And like any good biochemist, he figured he was screwing up, or the equipment was faulty, or the substrate was more cursed than usual. Lucky for him, after weeks of smashing into a brick wall of failure, he started asking other people, who also kept failing and then they figured it out.
