Can You Dig It?

I was chatting with a colleague the other day about all the new airport facilities being built in the UK, and the new roads too, and we were wondering how on Earth we are going to be able to get rid of it all and reclaim the prime arable land underneath after the oil peak.

No fossil-fuel powered diggers . . . fancy digging up a runway with a pick-axe? No - me neither.

We came to the conclusion that the best way to do it would be to plant trees as close to the tarmac/concrete as possible. Over time, as the trees grew, their expanding roots would destroy the road/runway, and do all the hard work for us. Obviously trees have the advantage of atmospheric cleaning and wood-fuel and building material by-products.

And for a while, we would have beautiful tree-lined motorways and runways :-)
