Heather Kerr and Emily Potter, guest-editors of a special section, Ecologies and Environments, address the urgent need to re-evaluate relationships between the human and the environmental, the cultural and the ecological, the technical and the natural. Here they showcase cultural studies work that vitally engages with the ethics, aesthetics and politics of ecologies and environments. Features writing by Martin Harrison and Katrina Schlunke, an artist's talk by Janet Laurence, and essays by Deborah Rose, Ross Gibson, Gay Hawkins and Emily Potter, Paul Carter, and Devleena Ghosh and Stephen Muecke.
