I was a vegan for 10 years, now I only eat meat. I bought into the sustainability argument for a long time.

I will not return to a plant based food diet -- and many people will agree with me, often quite aggressively. Eating beef is so important that I will spend my last dollar buying that expensive hamburger.

What I am trying to say is your line of coercion is a waste of time and doomed to fail. You cannot force dietary habits on people with an argument of sustainability. I don't care if the planet ends, I just want my damn steak, and that is a primal urge far stronger than sustainability ethics.
