London's Natural History by R S R Fitter
 
London's Natural History describes how the spread of man’s activities has affected the plants and animals in them, destroying some and creating others. 
 
Up to now there has been no real attempt to write a comprehensive history of a great human community in terms of the animals and plants it has displaced, changed, moved and removed, introduced, conserved, lost or forgotten. In selecting London as an area for such study
 
Mr. Fitter, himself a Londoner, takes the world’s largest aggregation of human beings living in a single community and in many ways the most interesting perhaps of all regions of the British Isles, and shows how the spread of man’s activities has affected the plants and animals in them, destroying some, creating others.
