This document provides an introduction and literature review for an undergraduate dissertation analyzing John Christopher's novel The Death of Grass and J.G. Ballard's novel The Drowned World. It discusses how the novels were early works of "cli-fi" that predicted issues of food security and global warming. It reviews how the novels fit within the literary context of 1950s disaster fiction and analyzes how they critique post-war British society and culture. The document outlines how the rest of the dissertation will explore the historical context of the novels and frame them within contemporary ecocritical theory to argue they were pioneering works of environmental fiction.
