Climate change: We have never faced a more critical time on our planet

My father used to say that, through culture, humans effectively domesticated themselves.

I ... believe the study of human history remains important and should not be banned. We should ensure that any archaeological studies are conducted with sensitivity and respect. Reburying relics, in my view, does not help anyone go anywhere.

Sadly, I am not able to take part in the fieldwork myself so much anymore, as both of my legs were amputated following an airplane crash twelve years ago.

The greatest problem we face is the growing number of people living in poverty. The related sense of hopelessness has to be impacting on every part of environmental management.

In the area of species protection, we should concern ourselves with what is right as opposed to what might be easier, or popular in the short term.

When out fossil hunting, it is very easy to forget that rather than telling you how the creatures lived, the remains you find indicate only where they became fossilized.
