While it should be a top reason, it's an extremely unpersuasive reason in the real world because people want their bacon burgers so long as they don't have to see what happens in a slaughterhouse or pay for the total cost of externalities of their consumption lifestyle choices.
There are much more pressing, self-interested reasons to advocate veganism:
1. Meat ag and bushmeat lead to pandemics: bovine tuberculosis, "Spanish" flu, Nipah, SARS, H7N7, H1N1, MERS, COVID. There are others.
2. Meat ag abuses the same antibiotics humans take (but manufactured in the veterinary supply chain) for purely economic reasons (mostly, to make animals grow faster) leading to the evolution of antibiotic resistant microbes and making antibiotic medications in humans less effective.
3. Climate change. It contributes 1/6 of all human GHG activity.
4. Air, soil, and water pollution are the result of mega grain farms, large pig farms, and CAFOs.
5. It's resource intensive and drives up the cost of all food by shunting more water, diesel fuel, arable land, etc. to less output.
6. Along with palm kernel oil, it's a leading driver of old growth deforestation.
7. And it hurts both the cute and the ugly critters.
Yeah. Sigh. I'm realistic because the "meat is murder" with gross-out signage of slaughterhouse porn billboard-sign-on-cars approach hasn't really taken off.
In other news, Moolec is developing GMO "Piggy Sooy" to taste like pork by inserting pork genes into beans. (I'm wondering: will it be Halal or Kosher?) Impossible Foods' "beef" relies on heme from GMO yeast, while Moolec plans to have GMO "beef" too.
Unleavened bread baked in a microwave oven still grows to a volume intermediate between traditional unleavened bread and bread leavened with yeast or baking powder.
I actually prefer the taste of such microwaved unleavened bread that I make myself and I also prefer the fact that due to its higher density and cohesiveness (in comparison with bread leavened with yeast) it requires more vigorous and more prolonged chewing, which is healthy for the teeth (and for dental implants) and it causes greater satiety.
