Sustainability requires that we demand enduring quality. Steve Strong has a slide presentation pointing out that much of Oxford was built 800 years ago. What are we building today that will be here 800 years from now? If something like that emerged from this recession, it would help justify the hardship so many people are currently experiencing.

Environmentally, business in America in 1970 was very similar to business in China today. Even if a CEO wanted to be a responsible corporate citizen, he (and they were all "he's" then) simply couldn't invest a billion dollars in pollution controls to produce a product that was indistinguishable from those of his competitors. His products would be priced out of the market. Passing laws that created a clean, level playing field for whole industries had to be a core focus of the 1970s.

We got everyone's attention, but we didn't solve any environmental problems.

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.

he economy favors throughput over quality and craftsmanship, and economists are terrified because the American savings rate has crept upward from about zero to almost five percent. But the mortgage crisis and the burgeoning credit card crisis are causing Americans to become wary of irresponsible debt.

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.

There really wasn't an environmental movement 30 years ago. The Sierra Club national office in 1969 consisted of one full-time volunteer.
