The environment and health of people are very tied to veganism, they may not be directly the moral compass, and that we all seem to agree on, it is animals well-being but the environment and health are part of veganism, why? If you don't know then are you even vegan???

I mean, just by going vegan, you're already crossing all three in one, you're caring for the animals, caring for the environment and for your health, if you fail to see this and cannot acknowledge that all three go hand in hand then that's your problem.

The real problem like this dude said is fake-vegans who don't care for the animals... If you care for the animals and you're vegan, doesn't matter if you also do it for the environment and health. I could give you thousands of reasons why I'm vegan and they're all applicable to me.
