This crucially important caveat they snuck in there:

“Prof Scarborough said: “Cherry-picking data on high-impact, plant-based food or low-impact meat can obscure the clear relationship between animal-based foods and the environment.”

…which is an interesting way of saying that lines get blurry depending on the type of meat diet people had and/or the quantity vs the type of plant-based diet people had.

Takeaway from the article shouldn’t be meat=bad and vegan=good - the takeaway should be that meat can be an environmentally responsible part of a reasonable diet if done right and that it’s also possible for vegan diets to be more environmentally irresponsible.

saves your battery

Maybe, maybe not. For OLED screens, where the pixels themselves generate the brightness, then an overall darker image will save power. For LCD screens with backlights it’s the opposite: the backlight is always on and the lowest power state of an individual pixel is to let the light pass through unmodified - the part that costs power is turning the pixel 9n so that it blocks the light to make a black dot. So, your statement isn’t true for all (or even most) devices.

Next: I find bright text on a black background to be hardest and most jarring to my vision. Humans have been reading black text on a light medium for millennia; it is natural. Light mode, for me, is easier to read and least tedious for my eyeballs.

I also just think that a light mode look is more polished looking…cleaner.
