The natural world is a web of elaborate, delicately balanced connections; even the smallest intervention can affect an entire ecosystem, leading to irreversible changes in the environment. For humankind to have an ontological understanding of how we are an intricate part of this equilibrium, it is important for us to realize that the disappearance of even a microscopic species in a remote corner of the earth can have catastrophic consequences. Biological Apocalypse: Species Extinction in the Anthropocene highlights our planet’s ingress to the Sixth Mass Extinction—a period conceptualized as the Anthropocene. Bringing together seventeen of the most susceptible non-human species falling into the International Union for Conservation of Nature (IUCN) categories of Critically Endangered, Endangered, Vulnerable, and Near Threatened, this volume inspires appreciation about the natural world, highlights the concept of species extinction caused by humankind, and examines how in the march towards ‘progress’, we have overlooked the rights of other species to flourish alongside us.
