Remember, soils and genes can be lost only once (irreversible). Soil losses reduce the planet’s capacity to store essential plant nutrients (all cations) and carbon (humus), both intimately linked to the presence of clay and, thus, intact soils. The number one driver behind this issue is growth in number of and consumption by humans.

Biodiversity is declining (in quantity and qualtity, i.e. fewer species and fewer individuals) for different reasons including over-use, over-harvesting, misunderstanding and direct destruction. The possible effects will concern at least agriculture (feeding human beings), health and the functioning of more natural ecosystems. It could be important to anticipate a little bit.
