Interim Progress Report
Four and one-half billion planetary orbitings (PO) since condensation, four billion POs since its seeding with self-replicating nucleic-acid oligomers, evolution on this planet has proceeded without atypical incident. Multiple extinctions of primitive lifeforms, brought on by a succession of geologic, cometary, stellar, and cosmic events have winnowed repeated surfeits of marginal lifeforms, typically eliminating 50-90% of unsustainable species with each cycle.
In the most recent million POs, the current dominant lifeform (DL) has developed, undergoing in the last five-hundred thousand POs an explosive, almost exponential growth, both numerically and technologically, to the point that its culture's environmental footprint now far exceeds the carrying capacity of this planet's resource reserves. As is typical in the first cycle of autonomous planetary lifeforms' self-extinctions, this DL's self-awareness of the consequences of its technological and reproductive success has not kept pace with that success. As a result this first-round of auto-induced extinctions is progressing smoothly for the DL and numerous other of the planet's species, owing to the toxic discharge of waste energy and material shed by the DL's expansion. The autocatalytic deterioration of this planet's environmental viability in the wake of this expansion guarantees a precipitous decline in planetary speciation in the next one-hundred POs or so, with probable elimination of all lifeforms requiring more than about two to three times the ambient stellar insolation per unit of each species' surface area: thus, the first cycle of bio-, as opposed to physically-, induced extinctions.
What the next DL will be, following resetting of the evolutionary clock by this imminent bio-induced extinction, and whether the next DL's conscious awareness of sustainable planetary energetic and material limitations will mature contemporaneous with its technological and reproductive competence, is impossible to predict at this point. It is worth noting that some of the most advanced members of the current DL are close to achieving such environmental awareness; but their societal organization, politically and economically, is predicated on extravagantly unnecessary waste production, which is the root cause of its impending extinction. Ironically, several primitive subcultures of the present DL, as recently as two-hundred POs ago, did co-exist sustainably with their local and planetary resource pool. But these subcultures were overwhelmed by a particularly aggressive, malignantly infectious subculture that has since grossly accelerated deterioration of the planetary biosphere's viability.
From a galactic perspective, it is fortunate that the self-destructive mechanisms of this aggressively consumptive subculture have hastened its extinction progress, else its contagion might spread to other planetesimals in this stellar system. Indeed one successful attempt to land specimens of the DL on this planet's sole satellite was accomplished some forty POs ago but the specimens were withdrawn and there has been no further repetitions of that behavior owing principally to the DL's propensity for fratricidal, inter-tribal conflict in their own terrasphere.
At present the DL has sent mechanical probes to other planets in the local stellar system but without reproductively capable specimens. Although no pre-emptive engagement or action is required at this time, owing to the DL's pattern of self-destructive, self-limiting behaviors, it is essential that the quarantine of this planet continue and its DL be closely monitored to assure that no viable specimens emigrate beyond the gravitational frontier between this planet and neighboring planetesimals. This policy, and whatever necessary supporting actions, are invoked in order to assure the DL's complete, spontaneous auto-extinction, thereby avoiding risking spread of this pestilential lifeform elsewhere in this or other galaxies.
