LOL . . . It would be even funnier except some people really think it can be done.
Does anybody here remember The Biosphere Project? (Look up Space Biosphere Ventures.)
This was the original study community for colonization of Mars, with a dome, and if you decide to go, be prepared to eat cockroaches.
(I did some preliminary engineering drawings for the framing of it back about 1986.)
8 People actually tried to live under this big glass bubble (actually more of a pyramid) for 2 years. Not as big as Brooklyn, but it was a completely closed and self-contained ecology.
Totally sealed off from the world. They demanded a 100 year guarantee on the sealant, because it
absolutely could not leak air! but they closed it down in under 2 years because everyone almost died from lack of oxygen. The CO2 from ordinary farming etc. was uncontrollable. It consumed oxygen faster than the plants could produce more. From Wikipedia:
Biosphere 2 suffered from CO2 levels that "fluctuated wildly," and most of the vertebrate species and all of the pollinating insects died.[14] Insect pests, like cockroaches, boomed.
The cheap movie they made there, about people dying in a dome, was a flop as well.
Dome living was a total failure, and yet people are still talking about going to Mars to build a dome, when we couldn't make a closed dome society work right here on Earth.
I'm just
waiting to hear how they've solved these issues.
