Man’s Relationship to His Environment 
process’’; this ethic, combined with a social conscience, would 
derive from a sympathetic attitude to life and culture in its 
various manifestations, leading man to realize his obligation 
towards the biological context as well as to humanity. Secondly, 
environmental modification must be guided by an environ- 
mental art—an architecture—which not only integrates 
experience, knowledge and ethics in creative design and 
development, but which in the very act of integration and 
design becomes exploration of environmental realities and 
values. In thus adopting the function of responsible agents of 
natural and environmental evolution we may hope at times, 
to fulfil our humanity. 
VARIETIES OF THE MAN-ENVIRONMENT RELATIONSHIP 
Under more or less permanent climatic and geological 
conditions, and barring unusual biological events, there exists 
only one ecological climax development in a landscape which 
is devoid of human influence. But in the history of the human- 
ized landscape, there are many “climax”? developments 
because of the changes in the ecological réle fulfilled by man. 
To the extent that a species is characterized by occupying a 
particular position and fulfilling a specific function in an 
ecological community, man, by virtue of his cultural differences 
and their development in time, represents (as it were) a 
multitude of different species. In respect to the environment 
man is not a consistent biological unit preserving its identity, 
but an organism in the process of change. We must therefore 
consider a wide range of environment contexts. In the following 
pages I shall give examples of such contexts, as related to human 
mobility, sedentariness and urbanity. In these brief descriptions, 
a community’s characteristic manner of using land, space and 
time is shown to emerge from or to result in a pattern of human 
rest and movement in the landscape. This pattern modifies 
nature, forms the humanized environment, and implies the 
creation of specific values in the man-environment relationship.
