39 Ways to Save the Planet: Wood for Good - a podcast by BBC Radio 4

Tom Heap introduces an episode of Radio 4's new environmental podcast which looks at 39 great ideas to relieve the stress that climate change is exerting on the planet.

Trees soak up carbon dioxide, trees store carbon dioxide. So why not build with wood instead of concrete and steel? The usual reason is strength, but Dr Michael Ramage at Cambridge University has what he thinks is the answer- cross-laminated timber. It's strong enough to build a skyscraper and replaces lots of that carbon from conventional building. Tom Heap and Dr Tamsin Edwards take a look at the global possibilities of cities built of wood.
