Multiethnic literature of the United States has repeatedly engaged with environmental matters, but its representations of “nature” and “environment” do not necessarily conform to the preservationist framework of mainstream environmentalism. This chapter provides an overview of the field of ecocriticism, which falls under the umbrella of the environmental humanities. Ecocriticism, a shorthand term for environmental criticism, denotes the study of literary and cultural engagements with the environment. Out of some intellectual conversations has emerged one of the more interesting trends in the environmental humanities: the infrastructural turn. Infrastructure has become a productive site for scholarly inquiry in the humanities and social sciences given its material and metaphoric qualities: it encompasses both technical objects with practical functions and aesthetic and semiotic vehicles imbued with forms of desire and fantasy.
