Whitney A. Bauman calls attention to the historical, political, and ecological influences shaping our understanding of nature, religion, humanity, and identity. He collapses the boundaries separating male from female, biology from machine, human from more than human, and religion from science, and he encourages readers to embrace hybridity and the inherent fluctuations of an open, evolving global community. As he outlines his planetary ethic, Bauman concurrently develops an environmental ethic of movement that relies on the daily connections we make across the planet. He shows how both identity politics and environmental ethics fail to realize planetary politics and action.
