Because eating animals is not only cruel and unnecessary, it affects other aspects in the environment. Remember water isn’t infinite. Take care of it now that you can.
I eat meat. AND I respect you for being vegan. I wished I would have so much strength in myself to do the same but I just have other things to worry about. I eat bio though. And I'm totally against animal abuse. I find your answers a little harsh. It seems like you don't respect any other lifestyles than yours?
