Many of us think of man as "dominating and destroying the world", to the point where we forget how resilient nature is. Came across this interesting photo essay from Telegraph Travel on places nature has come back. Well worth a look, I think, so here's a link to that.
Can you think of other places where nature has come back and almost hidden the work of man? One I can clearly remember are the Mayan ruins of Central America. Until they were dug out, centuries of abandonment had caused them to be obscured and covered by the jungle.
