A very interesting documentary directed by Jennifer Baichwal where the Photographer Edward Burtynsky travels the world observing changes in landscapes due to industrial work and manufacturing. I saw it a couple of years ago in Thessaloniki’s documentary festival and I believe it sets a different perspective of what we think the landscape is and means.
