Sustainable stadiums

I found a quite cool site about some eco-friendly, sustainable, unic and certainly beautiful stadiums around the world. We have already seen some of these huge arenas recently like the Olympic stadium in London this year during the summer olympics and we will be more familiar with some of them in the near future, like for instance the 2014 Winter Olympic stadium in Sochi, Russia. They contribute differently to a sustainable future which you can read shortly about. Some of these are for example covered with huge solar panels, photovoltaic panels or rainwater harvesting systems. Maybe we have a few preconceptions about stadiums in general because of bad influences on the environment? These comparatively green arenas are supposed to change our point of veiw I guess.
