Lol you just pointed out the lack of discipline in your reply. You're aware of how bad eating meat is for the environment and ethics. And I'm sure you'll understand, if you are educated on nutritional science, that it's also bad for your personal health.
And yet, you "really love to eat meat." Either you're too lazy to give good plant-based meals a shot (and time for your taste buds/gut to change), or it's just a discipline issue to stay away because meat is so conveniently engrained in our culture
