In an interview with The Telegraph he....
... expressed the fear that food would run out because of the damage being wreaked on the earth's soil by scientists' research.
He accused firms of conducting a "gigantic experiment I think with nature and the whole of humanity which has gone seriously wrong".
"Why else are we facing all these challenges, climate change and everything?".
Yes, indeed, why else?
I mean I'm not a scientist or anything (well, not a practicing scientist) but I'm pretty sure that there's not a gigantic experiment with the whole of humanity and all the earth that's causing climate change and reducing everything to some kind of radiating rubble.
But, if it's somehow escaped my notice and it's true, I'm betting Dick Cheney's behind it.
