What can change the culture?

Although we can talk about how it should be morally unacceptable to cause a nonhuman pain for our own benefit, for most of us, it won't change our meat eating habits.  It's a large part of our culture to consume meat and it's become a large part of our everyday lives. What could put us in the right direction of breaking  this habit? When pondering on the question, I believe it would be beneficial for citizens to be aware of the real facts.  If what happened in slaughterhouses or how these animals are fed and kept were shown to everyone all the time, the culture would change.  If information concerning nonhuman consumption was very accessible and was encouraged to be acknowledged, we wouldn't have an ignorant culture and the moral status of these nonhumans would be stronger.
