Today we're living in an era in which the biggest threat to human well-being, to other species and to the Earth as we know it might well be ourselves… - David Attenborough

Ever since we arrived on this planet as a species, we've cut them down, dug them up, burnt them and poisoned them. Today we're doing so on a greater scale than ever […] We destroy plants at our peril. Neither we nor any other animal can survive without them. The time has now come for us to cherish our green inheritance, not to pillage it – for without it, we will surely perish.

Reptiles and amphibians are sometimes seen as simple, primitive creatures. That's a long way from the truth. The fact that they are solar-powered means that their bodies require only 10% of the energy that mammals of a similar size require. At a time when we ourselves are becoming increasingly concerned about the way in which we get our energy from the environment and the wasteful way in which we use it, maybe there are things that we can learn from "life in cold blood."

The thing about a bush baby is that the male establishes its territory by peeing on his hands and putting it all on the walls. And after you've had a pair for about six months, you can see people coming into the house, sniffing and going: ‘Now, that’s definitely not mulligatawny soup.’
