A Debacle is a catastrophic evolutionary failure.
A debacle occurs at the end of a planet's evolutionary development when a species fails to reConnect. A debacle occurs because a disconnected species cannot handle the powers provided by advanced technological and administrative capacity.
A debacle is characterized by ecological, economic, social, political, and military spiral into self-destruction. A debacle occurs when technological/military advancement outpaces the emotional, psychological, and spiritual development of a species.
Debacles typically do not wipe out a species, but they can cause an inordinate amount of unnecessary suffering, and they can set a species back several decades or more, depending on how catastrophic the debacle.
