So the problem I have with most “ecological science fiction” is that it draws almost exclusively on the ideas of Malthusian economics—essentially, the argument that Thanos was right. The problem with this is that Malthusian theory has been disproven by every generation of humans to live on this planet for the last 150 years. It’s even more discredited than Marxism, which is another unscientific philosophy that “ecological science fiction” draws heavily from.
I remember an old 70s novel I picked up from the local used bookstore, where by the year 2000, Earth had warmed so much that Antarctica was the only habitable continent, and resources were so scarce that the main character—a buxom blonde—had to go topless. Yeah, very 70s. The premise of the novel was so absurd on its face that I couldn’t finish it.
I also remember an Octavia Butler book that I read. It was the sort of book that makes you chuck it at the wall once you’re finished. The plot went something like this: the main character has been abducted by aliens and drafted into their breeding program, and she spends the whole book trying to escape, only to learn that she’s already pregnant and never will. The end. The writing was pretty good, but the story was so horribly unsatisfying that I haven’t read anything by her since.
From what I can tell, most “ecological science fiction” is like that. Very pretty sentences, but horribly unsatisfying stories, with way too much preaching about how capitalism is evil and humans are destroying the planet. That’s probably why these books tend to win so many Hugo Awards.
Red Mars was okay, but it was less about Earth and more about Mars itself. I was personally more interested in the political intrigue among the colonists than the terraforming project, but both were pretty good. The characters all seemed a little bland to me, though, and I never really latched on to any of them, which is probably why I didn’t read the other books. From what I can tell, they got more preachy toward the end.
Everyone praises Dune for being an “ecological” novel, but to be frankly honest I never really got into that. The political intrigue and the struggle of Paul Atreides with his prescience was a lot more interesting to me, and while the ecological bits certainly played into the plot, I didn’t really care enough to pay much attention to that.
Also, the parts that I did pick up seemed pretty unbelievable to me. From what I remember, there was a second, much smaller type of worm that produced a certain kind of excretion which, if mixed with the spice, would cause a chain reaction that would completely destroy the Arrakis ecosystem. Something like Kurt Vonnegut’s ice 9, which instantaneously freezes any water it comes into contact with, which makes it the most dangerous substance on Earth because a single drop could freeze all the water on the planet. In my (albeit limited) experience, ecosystems always find their own equilibrium, which makes them resiliant against that sort of thing. But of course, that would probably interfere with the preaching that “ecological science fiction” tends to indulge in.
From what I can tell, Dune is one of the few pieces of “ecological science fiction” that hasn’t aged poorly, and that’s not because of the “ecological” bits, but in spite of them. Because the truth is that we live in a fantastically rich and abundant post-scarcity world, where “global warming” had to rebrand as “climate change” because none of the predictions came true, and the science has been so ridiculously politicized that the Green New Deal makes the Communist Manifesto look sane and reasonable.
Thanos was wrong. So too, apparently, is the entire field of “ecological science fiction.”
