Reckoning 5: Environmental Justice
They want creative writing about environmental justice. Their guidelines say, “Fiction preferably at least a tiny bit speculative, nonfiction preferably more creative than journalistic, poetry tending towards the narrative and preferably with some thematic heft, art leaning away from the pulpy heavily towards the political. But the heart of what we want is your searingly personal, visceral, idiosyncratic understanding of the world and the people in it as it has been, as it is, as it will be, as it could be, as a consequence of humanity’s relationship with the earth.” They actively seek work from Indigenous writers and artists, writers and artists of color, queer and transgender writers and artists, and anyone who has suffered the consequences, intended or otherwise, of dominant society’s systemic disconnect with and mistreatment of the natural world. Their website has specific details of the kind of work the prose and poetry editors want for this issue. They also welcome writing in Spanish, French or Swedish for potential translation, and work already translated into English, for which they pay the same rate to both author and translator.
Deadline: 22 September 2020
Length: Up to 20,000 words for prose; 3-5 poems
Pay: $0.08/word for prose; $30/page for poetry; minimum $25/piece of art
