...agricultural success that could sustain Biosphere's eight people for two years.In the real world, that kind of success can be found in something called a small farm. :') Thanks Daffynition. I remember a little of the coverage given this budding project by media sycophants; one of the participants was a self-described longevity expert who in interview explained that there's no reason the human lifespan can't hit 600 without any technological advances -- but that the laws of probability led him to the conclusion that surviving beyond that point would be basically impossible, because everyone would succumb to a fatal accident within 600 years. And of course, one drawback would be that the retirement age would have to be moved up to 575.
Impressive creds.
