It's not a category you hear much about so I'd like to help spread the word. maintains a growing database and good sampling of fictional novels, short stories, anthologies, prose, film, and other arts, including science fiction, literary fiction, weird and slipstream fiction, speculative fiction, and fantasy, with environmental themes or a strong focus on climate change. My only affiliation with them is that they listed my book, Halfway to the Truth. If you have an interest in environmental issues, then this website may be what you've been looking for, and is likely the largest collection of ecology related material available to your fingertips.
