Climate change, biodiversity loss, and environmental injustice are complex, messy, and gravely important issues. In addressing these concerns, traditional ecocriticism understandably has taken itself very seriously. Unserious Ecocriticism, by contrast, highlights alternative responses to the challenges of environmental collapse and catastrophe. By theorizing an unserious ecocriticism, contributors to this volume validate and empower alternatives to mainstream environmentalism, scholarship, and artmaking. The essays, artworks, and non-traditional scholarly formats of this edited collection demonstrate that the creative tools available to artists and those who study them are particularly well positioned to inventively disrupt normative modes of ecocritical presentation and environmentalist thought. Rather than approach environmental crises through tragic and dire warnings, contributors take seriously the unexpected or easily dismissed, play with format and form, embrace the bodily and abject, take pleasure in their subjects of study, have fun, and crack jokes. In Unserious Ecocriticism, humor, playfulness, parody, and irreverence become tools to challenge expectations, cope with complicated problems, and imagine new futures.
