This is probably not a popular opinion, but less environmental impact is actually more desirable to me than "no violence against animals". As far as I understand it, these sort of "animal protection" slogans only serve to make human beings feel better about ourselves, and as such could easily make us forgive (and forget) the massive amount of resources we consumed if not depleted on this earth. Simply by supplying for this huge amount of population, we have taketh away the right of other animal's possibility to have a thriving population. The human race thrived on a bloody ground, and we need to recognize that.
