Superwood

Anything made from oil can now be made from trees, so is a new age of wood about to dawn? Tom Heap visits Finland which is pushing for a new industrial revolution based on trees and plants rather than oil and coal. He takes a glimpse into a future where cars, clothes, computers screens, and everything else we buy could begin its life in the forest. And he finds out how the UK is leading the way towards wooden skyscrapers.
