Ecothrillers deal with the mostly invisible and intangible problems of climate change by searching for better ways of imagining its relations to nature and humanity. Ecothrillers present a global environmental crisis with variegated local effects that threaten all humankind but can still be prevented at the very last minute. The environmental crisis is mostly depicted as a result of anthropocentric dominion over nature, as a rationalistic ideology of progression and technological-economical exploitation of natural resources. The chapter (1) presents the impact of the Anthropocene for the humanities, (2) summarizes the characteristics of ecothrillers, and (3) analyzes prominent German-speaking examples by Frank Schätzing and Bernd C. Fleck while scrutinizing their different narrative patterns (precautionary, apocalyptic, dystopian, utopian) to contribute to a reflection on species agency.
