This paper seeks to address the importance of understanding the ambiguous term "sustainability" through the study of humanities, chiefly literature. Additionally, the paper explores the emerging genre of climate change fiction, or "cli-fi" and its potential role in presenting the issues of both ecological and human sustainability to a global audience, using Amitav Ghosh's novel The Hungry Tide as a primary example. As a basis for the theory that literature can affect a sustainable future, I also examine the importance of language in shaping both perception and protection of the environment. Language creates familiarity, which in turn creates consciousness. Literature then expands upon this consciousness to develop general understanding of the importance sustainability that can be easily understood and appeals to emotion in ways pure scientific data cannot.
