Guideposts for a Sustainable Future

Activities are sustainable when they:

1 - use materials in continuous cycles.

2 - use continuously reliable sources of energy.

3 - come mainly from the qualities of being human (i.e. creativity, communication, coordination, appreciation, and spiritual and intellectual development.)

Activities are not sustainable when they:

4 - require continual inputs of non-renewable resources.

5 - use renewable resources faster than their rate of renewal.

6 - cause cumulative degradation of the environment.

7 - require resources in quantities that could never be available for people everywhere.

8 - lead to the extinction of other life forms.
