The feeling that you do not wish to return to a place that you once loved and enjoyed when you know that it has been irrevocably changed for the worse. It is not topophobia where you can have fear of a place while entering it; topoaversion is a strong enough feeling to keep you from ever returning to visit the place that was once beloved.
As the pace of development quickens, topoaversion is likely to increase in many as a felt emotional response to the changes that take place. It is somewhat ironic, as special places on Earth become major tourism and eco-tourism destinations, that management of the impacts of increased visitation demands changes to the way people and their needs are met. The whole world has now become a bit like Mount Everest, where the actions of so many climbers and their support systems have turned what once must have been the ultimate ‘wilderness’ experience (alone at the summit) into the ascent of a huge garbage zone, complete with the frozen dead bodies of past ‘unsuccessful’ climbers. Jamling Tenzing Norgay, son of one of the first on the summit in 1953, has described contemporary Everest as “the world’s highest garbage dump”, as a result of the litter and abandoned infrastructure.
Topoaversion and ‘ecoaversion’ are now universal psychoterratic emotions. See Earth Emotions: http://www.cornellpress.cornell.edu/book/?GCOI=80140104119890
