Yann Arthus-Bertrand - "Earth from Above: An Aerial Portrait of Our Planet - Towards Sustainable Development"

Wandered through this, outdoors on the banks of the Yarra behind Fed Square, one Friday night a few weeks back. Impressively extensive exhibition of large photographic prints of vistas from all over the world, curated with lengthy text descriptions highlighting (environmental) sustainability issues relevant to the images. I didn't go through it all carefully, but it was good.
