Ecological Integrity:
A healthy ecosystem guarantees the vital resources: clean air, clean water, and healthy food.
Problem: Humankind’s impact on Planet Earth is approaching in magnitude the forces of nature.
Human population (P), consumption stimulated by affluence (A), and Technology (T) determine the human impact (I) on the ecosystem: I = P*A*T. (Paul Ehrlich).
Solution: All three factors must be reduced to restore and maintain ecological integrity.
