Agency in human–shark encounter

Agency in human–shark encounter

Agency in human–shark encounter Leah Gibbs ABSTRACT: Shark bite is exceptionally rare. And yet, representations of human–shark interactions are most often framed as inherently dangerous. The ‘shark attack’ trope has been widely critiqued as sensationalist and misleading. This image creates two further limitations: it offers a one-dimensional representation of sharks and overlooks crucial factors shaping
