Eco-ethical issues: Self-regulating versus subsidized ecosystems

SUMMARY

Sustainable use of the planet requires dependable delivery of ecosystem services at a level necessary to meet the needs of humankind. During the last two centuries, particularly in the twentieth century, ecosystems have been fragmented and stressed in a variety of ways, including biotic impoverishment. Self-regulating ecosystems are capable of maintaining nominative structure and function, including normal variability. Those ecosystems incapable of self regulation will require subsidies, which will divert resources from other activities that may also be important to sustainable use of the planet. If ecosystems are not subsidized, the loss of natural capital and ecosystem services will almost certainly impair the quest for sustainable use of the planet. Although most discussions of sustainability reflect an awareness of humankind's dependence on natural systems, ecosystem self regulation has not received an adequate amount of attention.

Key words:

• sustainability
