Apparently a new baby is born somewhere in the world every two seconds and the population is growing faster than we can cope so our friend's son who was born a mere five days ago has not been the youngest person on the planet for nearly his whole life.
They had an illustration of a city of the future which looked a lot like the photo above with little blinking dots showing the traffic. There were all sorts of interactive screens that explained stuff and there were displays of water pouring through rusty old Victorian pipes and salad plants growing in walls. There was an electric car I would like to been allowed to test drive and a weird Harley Davidson-style electric motor bike that you would need legs 10ft long to reach the pedals.
Then we ate our carefully considered lunch in this entirely sustainable building drinking tap water that we were assured was much better than anything that we can drink at home. We've now put The Crystal on to our list of places to bring future house guests which also means we can learn more about sustainable cities.
