Humans may live in the Anthropocene, but this does not affect all in the same way. How would the Anthropocene look if, instead of searching its traces in the geosphere, researchers would look for them in the organosphere, in the ecologies of humans in their entanglements with the environment? Looking at this embodied stratigraphy of power and toxicity, more than the Anthropocene, we will discover the Wasteocene. The imposition of wasting relationships on subaltern human and more-than-human communities implies the construction of toxic ecologies made of contaminating substances and narratives. While official accounts have systematically erased any trace of those wasting relationships, another kind of narrative has been written in flesh, blood, and cells. Traveling between Naples (Italy) and Agbogbloshie (Ghana), science fiction and epidemic outbreaks, this Element will take the readers into the bowels of the Wasteocene, but will also indicate the commoning practices which are dismantling it--back cover.
