Also Global Ecophagy.Consuming the biological environment. Coined and defined by Robert A. Freitas Jr. (Research Scientist Zyvex Corp). Frequently associated with "gray goo," as ecophagy (uncontrolled self-replication) is its main prupose. See "Some Limits to Global Ecophagy by Biovorous Nanoreplicators, with Public Policy Recommendations" where Dr. Freitas said "Perhaps the earliest-recognized and best-known danger of molecular nanotechnology is the risk that self-replicating nanorobots capable of functioning autonomously in the natural environment could quickly convert that natural environment (e.g., "biomass") into replicas of themselves (e.g., "nanomass") on a global basis, a scenario usually referred to as the 'gray goo problem' but perhaps more properly termed 'global ecophagy.'"
