I think one of the reasons that most people are not vegan is because they don’t see the connection between hamburgers and cows or bacon and pigs. It’s not their fault, the meat and dairy industry are using this to their advantage. And it starts young. Children don’t see a cow and think, “I’m going to eat that.”
I didn’t see the connection until I was in college and I watched a documentary about factory farms in Biology. Once I saw what I was eating, I was horrified. Horrified that I, for the first 20 some years of my life, was eating meat, dairy and eggs. And I never thought about it or made that connection.
