so to make this short, and I say from personal experience, that the best way to convince someone to go vegan is for enviromental reasons. Because people are way more willing to listen to the numbers and the right side of the brain rather than the left emotional side to the brain. NOT EVERYONE CARES ABOUT THE ANIMALS. I see a lot of vegans trying to remark to others how the animals suffer, but its just an inefficient way sadly. You're wasting your time. People are willing to respect and listen to you when you take a scientific approach to it. PEOPLE CARE ABOUT THEMSELVES AND THEIR LOVED ONES. So when they realize factory farming is bad enviromentally it implies its bad for themselves and therefore are more willing to listen to you and change their ways. its a win win for all! thoughts? I say this from personal experience, ive had actual success making people change what they eat through this approach rather than the old moral approach which is just energy and time draining.
