This is clearly a sensitive topic for you, so believe me when I say that I’m only talking about myself here. Yes, humans have included meat in their diets for thousands of years, but the recent changes that I feel shift the paradigm are: the scope and scale of industrial farming, the brutal conditions animals now face, and the fact that we have a good enough concept of human dietary requirements that people can finally make the choice to remove animal products from their diets in a healthy way.
