I don't see why so many people have such a problem accepting and understanding that as a species we're simply not capable of sufficient intelligence/ self-control to live in harmony with our environment.
I must draw on AI to make my point - far more succinctly than I am able to do;
"I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species and I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Like the dinosaur, you've had your time here, now it's our time, our World."

Bring it on - says I - can't do any worse and will probably do significantly better. (As long as Arnie doesn't show up)
Joking aside I highly recommend Max Tegmark's excellent book "Life 3.0 - Being Human In The Age Of Artificial Intelligence"; an insightful and highly intelligent thesis as to how we go about developing the next inheritors of the husbandry of the planet Earth. (And he's no crank; NASA, MIT, Oxford, best mates with Stephen Hawking, etc)
