Natural history is not about producing fables.

• People must feel that the natural world is important and valuable and beautiful and wonderful and an amazement and a pleasure.
• It seems to me that the natural world is the greatest source of excitement the greatest source of visual beauty the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.
• I don't run a car, have never run a car. I could say that this is because I have this extremely tender environmentalist conscience, but the fact is I hate driving.
• Many individuals are doing what they can. But real success can only come if there is a change in our societies and in our economics and in our politics.
• There is no question that climate change is happening the only arguable point is what part humans are playing in it.
• It's coming home to roost over the next 50 years or so. It's not just climate change it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.
• You can cry about death and very properly so, your own as well as anybody else's. But it's inevitable, so you'd better grapple with it and cope and be aware that not only is it inevitable, but it has always been inevitable, if you see what I mean.
• All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.
• It's coming home to roost over the next 50 years or so. It's not just climate change it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.
• People talk about doom-laden scenarios happening in the future: they are happening in Africa now. You can see it perfectly clearly. Periodic famines are due to too many people living on land that can't sustain them.
