I have no doubt that the fundamental problem the planet faces is the enormous increase in the human population

I find it far more awesome, wonderful, that creation; our appearance in the world; should be the culmination, or at least one of the latest products of 3,000 Million years of organic evolution, than a kind of country trick, taking a rib out of a man's side in a trance.

The fact is that no species has ever had such wholesale control over everything on earth, living or dead, as we now have. That lays upon us, whether we like it or not, an awesome responsibility. In our hands now lies not only our own future, but that of all other living creatures with whom we share the earth.

There is no question that climate change is happening; the only arguable point is what part humans are playing in it.

This last chapter .. may have given the impression that somehow man is the ultimate triumph of evolution, that all these millions of years of development have had no purpose other than to put him on earth. There is no scientific evidence whatever to support such a view and no reason to suppose that our stay here will be any more permanent than that of the dinosaur.

London has fine museums, the British Library is one of the greatest library institutions in the world... It's got everything you want, really.

An understanding of the natural world and what's in it is a source of not only a great curiosity but great fulfillment...
