“The sustainable forests of Europe take just seven seconds to grow the volume of timber required for a three bedroom apartment, and 4 hours to grow a 300 metre super-tall skyscraper. Canada’s sustainable forests alone yield enough timber to house a billion people in perpetuity, with forested trees replenishing faster than their eventual occupants.”
An excellent video from the Centre for Natural Material Innovation at University of Cambridge, looking at the sustainable homes of the future.
