This is extremely important. Most people have a very skewed perspective on what it means to be in the global 10% or 1%. I think this paper would be much more impactful if the authors listed the calculations used for defining these groups in the Methods section. Ideally the cutoff for each group should even be in the abstract so people can understand what 1% or 10% even means.

Even if this is true (and I've never been able to find credible evidence it is), what we're seeing now is just the upper bound of sustainable plant-based food production. As they scale it up and take advantage of technologies like precision fermentation, all evidence suggests this will continue to improve even further. Compare that to animal agriculture, where thermodynamic limitations on increased efficiency are strong, and most of the options to increase sustainability come at the cost of terribly inhumane practices.

The seaweed diet is just the result from a single study that has yet to be widely replicated. I'd caution against putting the fate of the planet into the hands of miracle cures until the scientific process can do its thing.

Even if the seaweed diet does help, the fundamentals of thermodynamics dictate that eating animals will never come close to the efficiency of eating plants, fungi, and microorganisms. Cows, chicken, and fish spend most of their energy living (to whatever extent spending every hour of your day in a windowless cage can be called living).

You can get them from the same place the fish get them from, algae! Like many micronutrients, fish don't actually produce them, they just accumulate them from non-animal sources. Unfortunately they also accumulate heavy metals, so they're not the cleanest source. Much better and more sustainable to go straight to the source.

Hi! I'm not a veterinary nutritionist, but I did used to teach metabolic biochemistry, and I spoke to a few veterinary nutritionists before putting my own dog on a vegan diet. Dogs are omnivores, so there are many vegan diet options dogs can live on healthily and happily. We like to think of dogs as friendly wolves, but they evolved a significantly different metabolism to co-exist with humans. I use a combination of Wild Earth and Bramble. Cats are obligate carnivores, so they require some chemicals (most notably Taurine) that don't naturally occur in plants. But there's no strong scientific barrier to us creating vegan cat diets through supplementation in the near future.

When I was in middle school I was sure I had cracked the meaning behind 42. I sent Douglas Adams a letter telling him how much I appreciated the books and laying out in detail how the alphanumeric values of each major character's name related to 42.

He wrote back an exceedingly kind hand-written postcard informing me that he appreciated my curiosity but that there was, in fact, no deeper meaning to 42 other than it was a nice-sounding number.

B12 is largely misunderstood. B12 isn't produced by any animals, it's only produced by certain bacteria. It used to be available in plant based diets, but modern hygenic practices have more or less stopped that. In modern industrial farming it's common for the animals to not get enough B12 either, so they often get B12 from supplements as well.

Fortunately it's incredibly cheap to synthesize supplements and you don't need much of it at all, so this is not really a concern for vegans.

Can you elaborate? I'm reading your argument as "This is not such a big deal because there are other horrifying things that are an even bigger deal", but I'm guessing that's not what you mean. Are you saying this will resolve itself _naturally_ in time? And if so, what gives you confidence?

My favorite use is in a photo booth I set up. It controls two cameras (webcam for preview, DSLR for the actual photo -- hopefully the RPi 4 will be me enough bandwidth to drop to just the DSLR), outputs to a printer, and drives a monitor. And the whole thing fits in a nice little suitcase.
