This book proposes an interdisciplinary investigation into contemporary ground-based promises of a green transition. In the context of ongoing earthly troubles, these promises have been approached through the processes of de-stratification and re-stratification in which they unfold. The postface reflects on the lessons learned from the various chapters. Throughout the contributions, the notions of “loops,” “leaks,” and “rhythms” emerge as critical tools for analyzing how and why the processes of strata formation are political. These notions materialize our relations with broader earthly “cycles” in space and time. The bio-geo-socio-chemical “loops” generated in pursuit of ecological transition represent a process of entre-capture: They incorporate earthly “cycles” into the infrastructure of human ways of life while simultaneously situating humans within an unpredictable material world. These notions invite a reimagining of strata, highlighting the political and often precarious entanglements through which people and the ground connect and co-constitute one another.
