Astrid wrote:Firstly being vegan is a naturally choice for the human body The only supplement that a vegan needs, that meat eaters get through their diet, is a supplement of b12. Now b12 comes from an earth bacteria that most animals (and humans before modern life) would consume because the vegetables and plants eaten would have some dirt on them. However today we clean our vegetables very meticulously and thus the naturally way of getting b12 has become a bit unreliable and thus as a responsible vegan you will do good to supplement that to be safe. Although b12 can be stored in the body for years and I do have friends who don't supplement b12 and instead go get their levels checked at the doctor every 6 months instead. But other than that everything the body needs is available in a whole food plant based diet. I would recommend the documentary "Forks over Knives" as good easy digestible presentation of the science behind the wholefood plantbased diet (and how it fixes a lot of the lifestyle diseases that challenges today's society).

If all the crusaders who spend so much time and energy telling people we need less cows put it into telling people we need less people, it would ultimately be better in my opinion. We need to get below zero population growth worldwide. Way below. I opted not to have kids decades ago for this very reason. As well as cutting down on the captive breeding program for humans, we need to start putting the earth's health ahead of our own health obsessions.
Cutting the population won't be fun, but neither will the alternative. I'm sure if there were a couple of billion less humans, there would be a lot less cows cluttering up the place.

Doesn't sound like anything that a normal person might want to take up! B12 isn't found in useful amounts in normal soil.
