Personally, I'm not willing to drive the world into an economic malaise so that someday my grandkids can see a coral reef on vacation.
The global (or U.S.) economy does not have to suffer; in fact, I think recent events indicate that our dependence on foreign oil and the tightness of energy supplies is far more important to economic health. There are measures that can certainly be taken that can reduce our dependence on foreign oil, increase the "robustness" and flexibility of the economy's energy sector without inducing an economic crisis or downturn.
And if we don't do something (or somethings) serious about energy, economic malaise might be wished for as a best-case scenario.
Agreed
