By 1975 - and continuing to today - all Americans came to believe that they had a "right" to a safe, clean, healthy environment. When I grew up, no one seriously criticized the steel mills and paper mills for the deadly stench they produced - that was the smell of prosperity. In the modern society, no one would tolerate such conditions in an American city.

The more subtle thing is more speculative. The world is well past its long-term carrying capacity for human beings living a European, much less an American, lifestyle predicated on planned obsolescence. International economic growth is largely a matter of accelerated movement of materials from mines and forests to the dump. Instead of saving and buying decent furniture we can pass on to our children, we charge our credit cards for shaped heaps of sawdust and glue that fall apart in less than three or four years.

Build high-speed, electrified trains over the most-traveled corridors. It'sreally hard to power carbon-free airplanes, but electrified trains are much easier. We'll be a half century behind the Japanese, but better late than never.

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.

By the year 2000, such renewable energy sources could provide 40 percent of the global energy budget; by 2025, humanity could obtain 75 percent of its energy from solar resources.

I would love to see a fundamental re-thinking of whether we truly want to be the world's largest debtor nation, feeding an insatiable desire for mall-crawling with cheaply made crap from all over the world.

Listen up, you couch potatoes: each recycled beer can saves enough electricity to run a television for three hours.
