Their reasons for doing what they do are working for them. We simply interpret these behaviors to our own so we can try to understand what makes them tick which in turn helps us to better take care of our world and everything in it. Whether we think any kind of animal is less intelligent then us or visa-versa, that is not the issue. We must remember that everything has a reason to be on this planet. We therefore must not look upon these precious lives as a dollar value.
Life is far more valuable then a piece of paper that is man made.
