, Referring to the fertility of the Nile delta, Andre? Voisin stated in 1960 that 'One often reads of the thousands of slaves that built the Pyramids for Pharaoh. In actual fact, these enormous edifices owe their existence in the main to the thousands of slaves inhabiting the sub-soil of Egypt' (Voisin, p.107, 1960.

. Deeb, Maha's specific research goals were to document the impact of microorganisms, plants, and worms on the constructed soil's properties and functioning, and to determine which plant and worm species were best at transforming urban waste materials into soil. She defended her thesis in 2016, and, along with her supervisor and colleagues, published her results in leading soil science journals, 2016.

, But she can do this only by invoking a generalised 'vital force', in all materials, which does not do justice to the particular mode of being of worms. For her, worms are in the same basket with 'stem cells, electricity, food, trash, and metals

. Lavelle, 1995: 23), which refers to how the molecules contained in the worm's intestinal mucus 'activate' the microorganisms that have the 'capacity' to alter organic matter chemically

M. Bouché, has addressed this specific problem by developing the concept of 'drilosphere', which has gained traction in the 'living soil' literature. The drilosphere encompasses the earthworm and the functional domain it creates and lives in, 2014.

, 2015) a processual understanding of the world starts with the idea that material things are immersed in currents of life. Similarly, for Whitehead, things, habits or organisms succeed in enduring, and their existence is always an achievement (Debaise, As we have seen with Ingold, vol.2017, pp.67-71, 2010.
