The author apparently believes that Biosphere 2 experiments proved that "humans can live in artificial ecosystems". While cockroaches and "crazy" ants multiplied, vertebrates died off along with the pollinating insects.
Biosphere 2 certainly proved Barnum's observation correct when Ed Bass spent $150,000,000 on the $250,000,000 project that he eventually placed under Steve Bannon's management - yea that Steve Bannon!
Even injecting oxygen and providing food from outside for the hungry 8 "biospherians" couldn't rescue the project.
If you drive to Tucson it's worth at least drive by. I think UA owns the property now, but it was in a sad state of disrepair the last time I dropped by.
The Biosphere 2 story has been known for decades. I'd be leary of anyone claiming that it was a success.
