  • The facts should speak for themselves, but we hardly ever let them. Each line of Mark Maslin's brilliant and comprehensive accounting offers a mesmerizing glimpse of humanity's appetite and ambition, blindness and brutality and capacity for self-destruction.

For laypeople like me, who can see what is happening but haven't always got the precise statistics to hand, it's hugely valuable. I think everyone should read it and absorb its contents: sobering, certainly, and more than a little frightening, but at least we won't be able to claim ignorance as we blunder on our destructive way.
