Sustainable Society:  A society that balances the environment, other life forms, and human interactions over an indefinite time period.

 

 

 

 

 


 

Population

Most students of sustainability agree that human impact and sustainability can be reduced to two interdependent factors: the numbers and living standards.

Or  I = P x A x T (John R. Holdren & Paul R. Ehrlich, 1971)

Where,
    I  = Impact
    P = Population
    A = Affluence
    T = Technology/Wastes

And

I = Population x Standard of Living

Simply stated, given a level of technology, nourishing environment, and balance with other life-forms, a higher quality of life can be sustained with fewer than with larger numbers of inhabitants. Moreover, at some point, it is probable that the numbers could overwhelm a sustainable balance.

These relationships and the numbers are the focus of the following pages.
