As a student of conservation biology, I believe that characteristics with survival value will ultimately prevail. There is no survival value in pessimism. If you think failure is inevitable, that view will probably become self-fulfilling.

There are a few obvious consequences and perhaps one subtle possibility. One obvious thing is that, to stimulate the economy, President Obama has committed to creating millions of green jobs that will leave a legacy - much as Roosevelt's public works did during the new deal.

I suppose I'd characterize myself as having a faith-based optimism. My faith is parental and Darwinian.

By 1975 - and continuing to today - all Americans came to believe that they had a "right" to a safe, clean, healthy environment.

An aggressive building performance standard for all new buildings, and a set of performance requirements to be met by all buildings before they can be sold (when upgrades can be included in the new mortgage). These should encompass heating and cooling, lighting, and plug loads. Coupled with new efficiency standards for appliances, lights, and furnaces, this should reduce the energy consumption of new buildings by 50 percent, more or less immediately, and go on from there.
