Laws of Sustainability .....

....Societies, or sectors of a society, that depend on population growth or growth in their rates of consumption of resources, are unsustainable.

Persons who advocate population growth and/or growth in the rates of consumption of resources are advocating unsustainability.

Persons who suggest that sustainability can be achieved without stopping population growth are misleading themselves and others.

Persons whose actions directly or indirectly cause increases in population or in the rates of consumption of resources are moving society away from sustainability.

The term Sustainable Growth is an oxymoron. 

The higher the standard of living one wishes to sustain, the more urgent it is to stop population growth.

If, for whatever reason, humans fail to stop population growth and growth in the rates of consumption of resources, Nature will stop these growths.

By contemporary western standards, Nature's method of stopping growth is cruel and inhumane.  

Glimpses of Nature's method of dealing with populations that have exceeded the carrying capacity of their lands can be seen each night on the television news reports from places where large populations are experiencing starvation and misery. http://www.thecircleforhumanity.net/
