The Global Collapse of Natural Biogeochemical Nutrient Cycling

This epochal transition describes the systematic, planet-wide failure of natural biogeochemical processes—specifically those regulating the cycling and availability of essential limiting nutrients like nitrogen (N), phosphorus (P), and critical trace elements—to sustain baseline primary productivity. The decline is not attributable to a single variable but rather the synergistic effect of elevated industrial pollution loads, cumulative climate forcing disrupting oceanic upwelling patterns, and resource extraction rates exceeding geological recovery capacity. By approximately 2035, global models indicate that the net flux rate for multiple critical biogeochemical cycles will fall below the threshold required to maintain pre-industrial agricultural yields in major sinks (e.g., the open ocean, deep continental soils).
