I saw something on TV the other night that was so beautiful and inspiring, I just had to share it here. The clever locals who live in the Meghalaya province in India have been building living bridges for what looks like hundreds of years. They train the roots of the strangler fig into functional bridges and ladders which can be used after about 10 years and can last up to 500 years. It's a very wet region and I imagine very poor too, so this is the perfect sustainable solution: a bridge that will stay put in floods and won't decay. Apart from the obvious environmental and economical benefits, these must also be some of the most beautiful structures around. You really should watch the video; it's from the very worthwhile show 'Human Planet' that's on Prime at the moment.
