Eco-gothic sounds like an interesting way of looking at certain books. It's wide-ranging enough, it seems, to take in something like Adam Roberts's The Snow (or J.G. Ballard's first four novels, for that matter) and Neal Asher's The Skinner. Maybe even Alastair Reynolds's Chasm City with its Melding Plague?

Er, okay. Sorry for "title-dropping," but it really is quite a fascinating idea.
