Mum just emailed me with an entry from her father's diary on 21st May, 1948
"Reading 'The Rape of the Earth' , a survey of world soil erosion by G.V. Jacks and R. O. White. Makes you think, and also a bit scaring. I want to stock up with at least 5 years' supply of of tinned provisions, in case man's stupidity with the earth means soon that the earth will not be able to produce enough to support man. Finely balanced nature hasn't a chance against man's industry, energy and science; later, man hasn't a chance against the revolt of unbalanced nature - deserts, floods, drought and sterile soil."
Plus ca change....
