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.

We shouldn't fuel the future with the polluting methods of the past, ... We have the technology to power our future in ways that don't threaten our health or poison our planet. Let's choose to use it.

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

Zeroes are important. A million seconds ago was last week. A billion seconds ago, Richard Nixon resigned the presidency. A trillion seconds ago was 30,000 BC, and early humans were using stone tools.

Politicians had always viewed environmental issues as narrow things of no great political consequence. Sort of NIMBY issues. A big part of the reason was that the groups that cared about wilderness didn't talk with the groups that were trying to stop freeways from cutting through inner cities, and neither of them talked to the folks who wanted to stop the military from dumping Agent Orange on Vietnam.
