Plant food contains (I think) 7 fewer amino acids than animal food. Those missing amino acids used in the generation of saliva, which is the first and the most important defense mechanism in the way to prevent infection. So Vegans need to get these amino acids as supplements generated chemically.
It is an unpleasant thought to kill anything, but it depends on the availability of food. There were many known cases when during the extensive famines people supplicated to eating animals regardless of the brain complexity considerations, even to cannibalism.
Thus, the more abandoned feed sources are produced on the planet, the further people will step away from the animal murder. However, if you go to Masai tribe that lives and dies by their cattle, it would be hard to convince them that killing the cow is bad. First, we have to provide for them an alternative source of food.
Arguments about tribal societies, third-world countries, poor areas, and so on, don't apply very well in first-world countries like the United States. The majority of Americans could easily handle major diet changes, if they had the will. You see this happen when people, wherever they live in the US, are advised by doctors to switch to eating less red meat, etc. From the perspective of environmental impact and general scope, tribal societies and extremely poor pockets of first-world countries are a tiny minority that aren't being thought of when people write articles advising more ethical diets. It's an interesting note, but they are exceptions to the rules that apply to most people who read such articles as this.

795 million people in the world do not have enough food. That's about one in nine people on earth. The vast majority of the world's hungry people live in developing countries, where 12.9 percent of the population is undernourished. Let's first feed them and then talk about diet.
