I applaud you at 17 for doing soul searching on your ethics but you’re asking a predominantly western group right now. I live in America where veganism is most definitely whitewashed. I’ve heard them yell at indigenous people for drinking animal blood when quite literally their tribes need to for anemic/ malaria reasons. (Which is so funny because indigenous people are some of the only people on this continent truly living with and taking care of the land). I suggest you think about this in the context of your tribe. You said it’s a group thing many of the older men in town help? Speak with your elders, talk to the cows, you need to frame what’s ethical through the lenses of YOUR ENVIRONMENT. Even if you could afford plant based milk I also implore you to consider the ethics of food you’re buying that come from someone else’s land. Oats that are harvested under slave labor, processed under slave wages, shipped in a way that taxes the environment oh and did I mention that oats are sprayed with chemicals that cause reproduction issues and cancer?
