Population Density

In planning operations, the most important value entering calculations for

d is , the population density.

where
s stands for the invariable, useable surface area and
p represents population.

This ratio reached a critical value decades ago.

Population density today exceeds the value allowed by the "ecological footprint", a measure to show how much land a population or individual uses for all its needs.

In d lies the one problem that must at last be recognized as the limiting factor for the quality of life. Because of an increasing d, this limit has been reached long ago in many geographic locations.

The only measure which will simultaneously solve a multitude of current problems, alas only for future generations, is to decrease population density. As available surface cannot be increased, a gradual decrease of population remains humanity's only way out of famine, war, terrorism and crime.

This unpopular though world-saving measure must be given priority even over socio-economic interventions.
