As a starting point for discussion, this formula may be helpful. If we agree that we live in a world of limits, then the variables can increase or decrease, but the formula must always balance, a requirement of(in the case of sustainability)staying within carrying capacity of our environment. We can then see the interplay between population numbers and quality of life. See the following website for further interesting insight: www.futures.hawaii.edu/j11/norberg.pdf.
