Unifying place
In 1923  the Association of American Geographers was called upon to make geography:
'...the science of human ecology... Geography will aim to make clear the relationships existing between natural environments and the distribution and activities of man... from the standpoint of man's adjustment to environment rather than environmental influence'.
The organising concept for geography was to be the region, in which the geographer synthesised elements of the physical environment with human activity to produce the image of an individualistic and well-defined spatial entity with a unique character, a particular living ecosystem.
