I've been vegetarian for 7-8 years and think it'd be great if everyone stopped eating meat, but expecting even a single person to stop who hasn't already expressed interest in it is pie-in-the-sky wishful thinking. We should not base our strategies for fighting climate change on hoping all of humanity will take a sudden 180° turn on their natural instincts to eat meat.
I watched a woman break down crying in a grocery store, the guy behind her put 40 lbs of ground beef on the conveyor. She started off as angry “how can you bear the thought of eating all that dead animal?” “Oh it’s not even for me, it’s for my dogs.”
I admire anyone and everyone who wants to be a vegetarian/vegan. Expecting the rest of the world to follow suit is a fools errand.
