When you say that veganism shrinks your brain, I presume you refer to Vitamin B-12, which is essential for a healthy nervous system and is not naturally found in plants.

B-12 does not originate in animals, it comes from bacteria which line the stomachs of animals. Similarly, if you took vegetables out of the ground and ate them without washing them you could get B-12 from the soil residue, though that would be unhealthy.

Vegans are not intrinsically B-12 deficient, as you suggest. They can get their B-12 through either vitamins or fortified foods. The B-12 is synthesized from bacteria cultures.

Two other points:

Indigenous people can cause environmental destruction, too. The first human settlers of Madagascar, New Zealand, and Easter Island were not Europeans or imperialists, but they wiped out species and caused environmental havoc just the same. Also, there is suggestive evidence that the first people to migrate to the Americas more than ten thousand years ago were responsible for megafauna extinctions. You can read about it in Jared Diamond’s “The Third Chimpanzee”.

The suggestion that vegans “are somewhat of cannibals” for eating anything at all necessitates an eye-rolling. Vegans are under no illusion that “kingdomism” is on any firmer ground than “speciesism”. Vegans do not think killing animals is wrong merely because they are animals, but because many animals (although not all) have the capacity to feel pain and suffering. At a minimum this would include vertebrates and cephalopods as groups of animals possessing “inalienable rights”. Other animal phyla do not possess a capacity for suffering. Sponges and corals are animals but are not seen by vegans as intrinsically morally valuable, so if they object to the death of a sponge or coral it would be for environmental reasons, not because of animal rights.

I also don’t agree with things like Animal Liberation Front, PETA, Greenpeace but love animals…am against animal cruelity. I know we have to eat meat…it’s biological. Vegans are doing their bodies some harm, at least in the brain area. No joke intended. Your brain will shrink without eating meat, at least fish or poultry. Not super shrinking and everyone would be affected differently but your brain does regulate more than thinking…i.e. breathing, hormone levels etc. Although, lots of red meat and egg yolks can be bad. However, eating vegetables also with meat and whatnot, is definitely good.

Even though it was partially hunters in the past that caused some wildlife population problems, you can even more blame settlers, logging, making big cities, pollution like pesticides. You know, people in general including those that are into animal rights. About the only people that didn’t decimate the land were the Native Americans who were orginally here, and maybe a few hippies. Not to say every Native American is always good. They fought amongst each other a lot too, you get the picture. People have to eat and if you wanna nitpick, we do share DNA with plants too…so you vegans are somewhat of cannibals.
