The zootopia theory

Aren't some of you familiar with the Zootopia theory?<br><br>It's an animated movie in which predators and prey live together. The movie starts with a presentation of how they lived in the past: predators hunting preys, and preys are afraid of predators.<br><br>Then some event that we don't know about happened and predators and preys started living together without any issues.<br><br>The problem is that we don't see what happened in the present world in order to go from hunters and preys to living together without any issue. Therefore it is impossible for us to know how to human beings can live together given our history.
