Effects on landscape,
Apart from intrusion of exotics there may be a lot of hogwash talked
about damage to landscapes by "modern man".
I recently attended a lecture based on a photographer returning to areas
of Derbyshire in the UK that had been photographed in 1856 by a party of
keen photographers. He had located the sites at which they had taken
photographs and taken his own for comparison. The most striking
impression that came across was the great INCREASE in tree growth in the
intervening 140 years in nearly all the views.
It struck me that this could be a very fruitful avenue of environmental
investigation. In the UK and US there was a huge explosion in
photographic recording in the 1870's and 1880's but I have never seen
this used as evidence of environmental change. (It could be taken even
further back by using landscape paintings).
Just a thought,
