We're not going to terraform Mars, but we're doing a good job of venusforming Earth.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Yeah, I've been meaning to read a City on Mars, it's near the top of my list. I have read some excerpts from it though, and from what I've seen, it is trying to tackle these questions from a realistic perspective, but it does also seem overly pessimistic at times.
Btw, your username is awesome.
