Honestly, I've just accepted, that animals are going to suffer for me to eat them. Now I'd like it, if they could lead happy lifes before I do so. But that is sadly not the world we live in.
Well yes but I
a) ascribe to most animals a lower level of consciousness to humans and
b) am very biased when it comes to that in as I don't want for anyone or anything to kill me.
Genuine question, what benefits do you mean? On the health side - since I went vegan + aiming for whole food plant-based, I've been the healthiest I've ever been. I wasn't even anticipating it, but I've lost a great amount of weight without trying and have more energy than ever. Definitely has cemented the switch as one of the best life decisions I've ever made.
I think the book How Not To Die by Dr. Michael Greger explains really well why. It discusses how animal-derived foods straight up are not good for you nutritionally. It also explains the health benefits of various plant-based foods in preventing different illnesses and supporting your immune system. I recommend it.
The more meat you eat, THE SOONER YOU DIE.
The more meat you eat, THE MORE MAJOR DISEASES YOU EXPERIENCE BEFORE YOU DIE.
