Why Do I Not Hear Environmentalists Cheering?

You know, Will Hinton has a point.  With gasoline prices skyrocketing, demand for oil will shrink.  Remember economics 101?  Higher prices equals lower demand.

The rapidly rising price of gasoline should put a ginormous dent in our consumption and therefore dependence on foreign oil.

Isn't this what the environmentalists want?  Why am I not hearing a victory cry?  Where is the cheering?  Why do I only hear whining about prices at the pump?
