The television show “Zoo” is about animals turning on humans. At this point, you might be tempted to say, “What took you so long?” One of the characters noted that without intellect and technology, man would rate a mere 2 out of 5 on the predator scale. But we do have the intellect and the firepower to destroy anything that gets in our way, be it man or beast. We take what we need and screw the rest. Will we ever evolve into a kinder, gentler species? Is there a next step, or is this the end of the line?
