Water Alchemy: Attila Bodnar at TEDxDanubia 2013

Our relation to water is ambivalent: when we are thinking about it we imagine the crystal clear source of life, yet in the urban area our water treatment is a mess. Literally. But wasting water like that is no longer an option. It's time to rethink our wastewater treatment in a new efficient, organic and urbanic way. Attila Bodnár shows us his idea of water renewal gardens, where the water cycle closes in a beautiful way.
