On YouTube, look up Earthlings. You have to watch the whole thing, it is a hard watch. But it changed everything for me. It took me a few hours to watch because I was in tears. But we owe it to the animals to know if we are going to continue using them. I’ve been vegan since that day.

Good that you are trying to change but go vegan not just vegetarian, because there is immense amount of cruelty in dairy, honey, silk, leather, wool etc

There's a few good documentaries that really highlight the horrific beast that the animal agriculture industry is. Dominion showcases how cruelly treated animals are. Gamechangers talks a lot about the environmental aspects of animal ag if that's your thing. I've heard Cowspiracy is good but I haven't watched it bc I'm already woke lol. There's a new one called Pignorant that's by a vegan activist I follow that I really like, too.
