While I agree wholeheartedly that the world needs to cut down on meat consumption, I do NOT agree with forcing it on somebody involuntarily. In some places, especially some parts of the US, cheap meat is often the only way for people to survive, and they do not have access to all the non-meat products they would need to completely replace every nutrient.
Being successfully vegan and maintaining health is a privileged thing in the US. Our food economy is centered on meats, salt, sugars, and fats which are cheaply available everywhere.
