roles, the role reproduction plays in defining gender, and the inequitable political or personal power of one gender over others. Some works have illustrated these themes using utopias to explore a society in which gender differences or gender power imbalances do not exist, or dystopias to explore worlds in which gender inequalities are intensified, thus asserting a need for feminist work to continue. Climate fiction, or "cli-fi," deals with issues concerning climate change and global warming. University courses on literature and environmental issues may include climate change fiction in their syllabi, and it is often discussed by other media outside of science fiction fandom. Libertarian science fiction focuses on the politics and social order implied by right libertarian philosophies with an emphasis on individualism and private property, and in some cases anti-statism.
