Great comment.  Dinosaurs were probably one of the most self-sustaining specious of all earth-time, and it took an extraordinary external event to finish them off.  Humans are different, however, in that we have acquired the means to kill off ourselves and much of the bio-sphere of out own volition, and relatively quickly.  This places an extraordinary responsibility on us not to do what we can do.  Dinosaurs probably didn't practice much self restraint, the earths ecology was strong enough to contain them for hundreds of millions of years. We have breached the boundaries of the Earths ecology and so we have to learn to practice self-restraint - and so far we haven't been able to practice it enough.
