At Animal Welfare Expertise, we find these new insights into rhino behavior both fascinating and deeply relevant to we

But here's the really interesting finding: animals are more flexible, changing from one outlook to the other more frequently than we do.     As humans, we tend to think of ourselves as either an optimist or pessimist. Society’s take on this is that th
