The proposed new geological era, The Anthropocene (a.k.a. Age of Humans, Age of Man), marking human domination of the planet long called Mother Earth, is truly The Age of the Motherfucker. The ecocide of the Anthropocene is the responsibility of Man, the Western- and masculine-identified corporate, military, intellectual, and political class that masks itself as the exemplar of the civilized and the human. The word motherfucker was invented by the enslaved children of White slave masters to name their mothers’ rapist/owners. Man’s strategic motherfucking, from the personal to the planetary, is invasion, exploitation, spirit-breaking, extraction and toxic wasting of individuals, communities, and lands, for reasons of pleasure, plunder, and profit. Ecocide is attempted deicide of Mother Nature-Earth, reflecting Man’s goal to become the god he first made in his own image. The motivational word Motherfucker has a flip side, further revealing the Anthropocene as it signifies an outstanding, formidable, and inexorable force. Mother Nature-Earth is that “Mutha’ ”—one defying translation into heteropatriarchal classifications of gender, one capable of overwhelming Man, and not the other way around. Drawing upon Indigenous and African American scholarship; ecofeminism; ecowomanism; green activism; femme, queer, and gender non-binary philosophies; literature and arts; Afrofuturism; and popular culture, Call Your “Mutha’ ” contends that the Anthropocene is not evidence of Man’s supremacy over nature, but that Mother Nature-Earth, faced with disrespect, is going away. It is imperative now to call the “Mutha’ ” by decolonizing land, bodies, and minds, ending rapism, feeding the green, renewing sustaining patterns, and affirming devotion to Mother Nature-Earth.
