“Does science fiction imagine human-induced ecological disaster because it is admitting defeat? I don’t think so. There are sf stories featuring flooded cities, extinct and exploited species, overpopulation, drought, toxic waste, and more, and I think writers are telling these stories (1) to remind us that we’re not there yet, and relatedly, (2) to urge us to avoid moving toward these futures by being more thoughtful about the artifacts we create.”
