Why can't we all just get along? Why are we not all happy?"

Many city-dwellers have a romanticized conception of the living world. From another perspective, some "conservation biologists" favour e.g. "". By contrast, I think any truly compassionate person should be horrified at the terrible suffering of Nature "red in tooth and claw". Why not aim for a cruelty-free world instead?
