I'm thinking we each make our own little ecosystem, maybe a half an acre would be enough. Maybe make it double walled, just in case, and then say screw it to everyone else as climate change and various other big things occur on the outside.

You might be interested in Biosphere 2 [1], a 3 acre hermetically sealed dome stucture designed to house about 8 people with an ecosystem to provide them with everything they need to survive. They didn't quite get oxygen and food production to the required level, but if you add another acre or so it should work. With renewed interest in moon and mars colonies somebody is bound to revive that line of research. 1: http…

TIL Steve Bannon was a director of that Biosphere, if only briefly.

Did anyone try introduce an animal in such a closed system, insects for instance. Does it self sustain ?

On a larger scale, wouldn't this be Earth?

Complete with the "put it in a spot with enough sun light". Except the atmosphere leaks a little http://www.esa.int/Our_Activities/Space_Science/Cluster_watc...

He has the right look. Perhaps he's a Time Lord?

There should be more funding and research on self contained, or nearly self contained ecosystems. The cost is modest on the larger scheme of things, but the potential benefits in the next half century could well be tremendous. Also, doing such research here on Earth may well save the lives of many pioneers in the coming decades.

Any one know what sort of jar that is? and/or where to buy one? Edit: its called a demijohn if anyone else was curious, used for making wine

They're also called, or very similar to, "carboys". Google says they're called "jimmy johns" in USA, but I've no knowledge of that.

demijohn are a bottle in a wicker wrapping. Once you get to large glass bottles like this breakage is real issue so it makes sense to wrap them so they can be moved with less chance of breakage. Note that if you do build one of these, be VERY careful moving them as they can break with a small slip and the large pieces of glass can easily cut tendons, leading to lots of long term issues.

53 Years. Almost certainly meant to include the word "half".

That is a much better theory then mine that AI wrote the article and just messed up a couple details.

I wonder what other life forms are inside that jar apart from the plant. Is the tiny sealed world a paradise or a hell for them?

If the soil was taken from the garden there should be hexapods within it. https://en.wikipedia.org/wiki/Springtail

Hm, hexapodia as the key insight?
