This dissertation considers the potential of desire to protect humans, animals, and the environment in the biopolitical times of late capitalism. Through readings of recent South African Literature in English from a postcolonial ecocritical perspective, this project theorizes desire as a mode of resistance to the neocolonial and capitalist instrumentalization of communities of humans and nonhumans, where they are often seen as mere "resources" awaiting consumption and transformation into profit. Deleuze and Guattari posit this overconsumption as stemming in part from capitalism's deployment of the psychoanalytic definition of desire as lack, where all desires are defined according to the same tragedy and brought into a money economy. By defining desire, capitalism seeks to limit the productive unconscious and attempts to create manageable subjects who perform the work of the capitalist machine--subjects that facilitate the extraction of surplus value and pleasure for themselves and the dominant classes. Thinking desire differently as positive and as potentially revolutionary, after Deleuze and Guattari, offers possible resistances to this biopolitical management. This different, positive desire can also change views of others and the world as existing solely for human consumption: views which so often risk bodies towards death and render communities unsustainable. The representations of human and animal desires (and often their cross-species desires) in this literature imagine relationships to the world otherwise, outside of a colonial legacy, where ethical response obtains instead of the consumption of others and the environment by the dominant subjects of capitalism. This project also considers other attempts to protect communities such as animal rights, arguing that rethinking desire is a necessary corollary in the effort to protect communities and lives that are made available for a "non-criminal putting to death" since positive desire precedes the passing of any such laws and must exist for their proper administration. These texts often demonstrate the law's failures to protect communities through portraying corrupt officials who risk the communities they are charged with protecting when their protection competes with government officials' personal capitalist ambitions. Desire offers opportunities for imagining other creative options towards protecting communities, outside of legal discourse.
