The argument was not that domes are small but that "The word "forest" is 
not even suggestive of domes. " Anyway, height is not the 
issue---breadth is the issue. At some point, it's no longer a dome but 
an airtight greenhouse. Whatever you say, you are filling in Wolfe's 
blanks with conjecture, however sound.

I didn't say domes didn't exist on Urth. But remember, you said there is 
no difference between forests and domed forests. Now it seems there are 
all kinds of differences. Which is it?

No. It's not "greener than not." It's GREEN. From your Earth analogy, 
it's 70% green.

Precisely. The whole thing about forests is that they admit anyone who 
enters them. Kind of hard to play Robin Hood on a world of airlocks.

Which is why it doesn't matter.

This is just dismissing facts. As I said, no one mentions that Lune is 
flashing or sparkly. Therefore, we are not meant to think that it is, 
nor are we meant to jump through hoops.to figure out why.

The main strength of your theory is that domes are another SF cliche 
that we might be expected to just "know." The more explaining you do, 
the weaker the theory becomes.

This is terraforming.

Right.

No. A miniplanet could be small enough to lack a native atmosphere but 
large enough to sustain a created one with help. Since you are appealing 
to advance technology, why not go in this direction?

Someone imported water and air, yes. So what?
