I finished Kim Stanley Robinson's
2312, and I really enjoyed most of it. Like most of my favorite sci-fi, it matches a pretty sweeping backdrop and heady ideas with a few solid, believable characters rooted in relatively straightforward problems. (IMO,
Iain M. Banks is still the master of this big, colossal universe and issues vs. two or three well-written, relatable characters).
Robinson isn't afraid to hide his agenda -- the Earth as we know it is going to be destroyed by human rapacity, and even colonizing other planets, moons, and asteroids (
mostly asteroids) isn't going to solve some basic problems.
The climax of the novel (SPOILERS!) is the "re-wilding," where the two main characters manage to stage a massive re-population of the Earth's wildlife and, by extension, a revitalization of our planet's ravaged ecosystem. The book really shines here, as Robinson matches a breathless narrative to some pretty complicated (for an idiot like me, at least) earth science / ecology issues.
Unlike Banks, Robinson doesn't seem to think interstellar travel will ever be a possibility for humans. And so the stakes become even higher for a fully revitalized planet. He suggests that the human species is so unconsciously tied to Earth that extended periods away from the planet will directly lower one's life-span. People who live off-Earth, "spacers," are common enough, but without the occasional trip back to our Mother Planet they basically stunt their own life-spans or go crazy.
This is the first Robinson novel I've read, and I'm curious to pick up
The Mars Trilogy, of which I take it
2312 is something of an addendum. Still, I had no problems going into this one "cold" without having reading some of his earlier work.
Also, his take on the future of gender norms and sex is pretty mind-bending. There are some moments of actual, literal poetry as well, which was welcome and unexpected in a "hard sci-fi" book.
Recommended.
