Instead of a cost analysis in the preserved ecosystems. How about we do an environmental impact study on the effects of drilling. Please remember what happened with the Valdez and the BP oil spill in the Gulf of Mexico. The opportunity cost needs to include the opportunity of not having the resources for later.

The acute lack of macroeconomic understanding and externalities is troubling at best.
