In page Kim Stanley Robinson:

"

Virtually all of Robinson's novels have an ecological component; sustainability is one of his primary themes. (A strong contender for the primary theme would be the nature of a plausible utopia.) The Orange County trilogy is about how the technological realm intersects with the natural realm, highlighting the importance of keeping the two in balance. In the Mars trilogy, one of the principal divisions among the Mars population arises from dissenting views on terraforming. Colonists debate whether the barren Martian landscape has a similar ecological or spiritual value when compared with a living ecosphere such as Earth's. The novel Forty Signs of Rain has an entirely ecological thrust, taking global warming as its principal subject.[citation needed]
