That might depend somewhat on your definition of life support.
It's not like we take a lot of stuff straight from the nature these days anyway.
As long as there's a good energy source, most other things can be recycled, and especially with the development of 3d printing, as long as you can use the material from old machines to make new machines, humans can survive for a very long time. Theoretically speaking.
And the rest is very much up to speculation.
Perhaps we should open our minds to genetically modified humans, better adapted for new environments?
The technology certainly starts to be there.
In a completely unrelated note, I actually came to post this.

Not long ago, researchers had thought it was rare for the cells in a single healthy person to differ genetically in a significant way. But scientists are finding that it’s quite common for an individual to have multiple genomes. Some people, for example, have groups of cells with mutations that are not found in the rest of the body. Some have genomes that came from other people.
