ABSTRACT
In this chapter, I argue that we, Homo sapiens, have an ethical duty to restore natural darkness to biodiverse, forested ecosystems. Historically, human beings have relied on forests for material sustenance and psychophysiological wellbeing. Utilising the philosophical concepts of wildness and relational value, I argue that we are thereby bound by reciprocity to (in return) mitigate forest-adjacent light pollution. After all, a variety of forest-dwelling species are negatively impacted by dwindling natural darkness, including (but not limited to) insectivorous and frugivorous bats, various plant (including tree) species, fungi, and a variety of nocturnal pollinators. In addition, the loss of natural darkness precludes human subjects from undergoing a variety of transformative experiences that are uniquely associated with immersion in dark, biodiverse forests. Finally, as old-growth groves disproportionately sequester carbon and are negatively impacted by light pollution, increasing artificial light at night indirectly (and worryingly) serves as a driver of global climate change.
