Environmentalists believe that monolithic solutions - be they in the auto, nuclear, or genetics field - are doomed to fail and lead only along the path to dependence. They feel rather that it is far more sensible to approach the future by opening up more possibilities. Likewise, polyamorists believe that monogamy sterilizes love and fosters unhealthy codependence, whereas multiple relationships feed off of each other's differences and ultimately lead to an enriching fulfillment.
