The above is interesting, but I'm afraid it's not realistic. Everyone vegetarian? Non-vegetarian people would see that as an untolerable infringement to their own free will.
Free will without responsibility is license. Those who continue with a meat eating diet are the only ruining there own health and are adding challenging karma to their soul. I am using license in this context;
freedom to behave as one wishes, especially in a way that results in excessive or unacceptable behavior:
"the government was criticized for giving the army too much license"
(a license to do something)
a reason or excuse to do something wrong or excessive:
"you do not have a license to break traffic laws"
