I made the statement that it wouldn't be possible until you can build a self sustaining environment here on Earth with no sunlight. So I guess I have a question that would probably be better for a TED convention or something but here it goes. What would be required to create a self sustaining environment without the use of any plants or animals? Is it possible to make the Goop from the Matrix that feeds everyone in real life?"
