As Galactic Standard Time and the route network became more sophisticated, the probabilities of disaster could be calculated with greater precision than before. Failures of atmospheric-control facilities, stellar explosions, epidemics, and ecosystem collapse were assigned probabilities in advance. One colony was calculated to have a 4 percent chance that its atmospheric circulation system would stop functioning within the next thirty years, while in another star system the probability that stellar activity would exceed the limits of habitability within eighty years was calculated at 0.6 percent. Most risks did not lead to actual disasters. Administrative agencies compared the scale of a risk with the cost of evacuation and moved residents only when the risk exceeded a certain threshold. As predictive technology improved, the number of people who fell below that threshold also increased.
If the probability of an accident was 1 percent, nothing happened ninety-nine times out of a hundred. But when the same judgment was repeated across the entire galaxy, sooner or later the remaining one time occurred. Whenever an actual disaster struck a colony that had not received an evacuation order, the earlier risk forecasts were made public. It became increasingly difficult to explain that the accident could not have been prevented. The risk had already been calculated.
During this period, ecological leagues, medical associations, rescue organizations, religious institutions, and groups representing disaster victims formed a loose coalition. Its first name was the Life Protection Coalition. Its demand was simple. Predictable deaths should not be left to occur because of administrative cost. The Coalition demanded passages and places to live for residents who wished to evacuate even when the level of risk fell below the official threshold. At first, the costs were covered by private fundraising. In many of the colonies that evacuated, no disaster actually occurred. Critics called these unnecessary evacuations. The Coalition replied that the fact that nothing had happened was not evidence of failure.
The first armed conflict occurred in Outer Zone 63. Stellar activity in the region was calculated to have a 2.1 percent chance of exceeding the danger level within seventeen years. The Galactic Disaster Agency did not issue an evacuation order because the probability fell below the 5 percent threshold for mandatory evacuation. The Life Protection Coalition began moving residents through its own transport network. More than half the population wished to evacuate, but the destination did not have enough habitation space or life-support facilities to receive them. The Coalition demanded access to emergency facilities in nearby colonies. The Disaster Agency refused, arguing that this could reduce the safety capacity of other regions. The Coalition occupied vacant emergency habitats and several reserve passages. The Disaster Agency ordered the facilities returned. The Coalition replied by asking how it could be illegal to use facilities built to save lives for the purpose of saving lives.
The conflict spread to several star systems. Colonies denied evacuation because their risk levels were low joined the Coalition, while star systems opposed to the compulsory redistribution of resources supported the Disaster Agency. Even during the war, both sides claimed that they were protecting more lives.
The predicted disaster did not occur at the star in Outer Zone 63. It remained habitable until the war ended. The government presented this as evidence that evacuation had not been necessary. During the same period, actual disasters occurred in three of the twelve regions from which the Coalition had forcibly evacuated residents. In one, the atmospheric-control network collapsed. In another, an eruption from a stellar sunspot rendered half the planetary surface uninhabitable. Most of the residents evacuated from the three regions survived.
The war ended when government forces retook the major passages. The Life Protection Coalition was not granted the right to occupy facilities and disbanded its military organization. Instead, the peace agreement guaranteed public access to disaster forecasts and the right to voluntary evacuation. Residents could request relocation even when the level of risk fell below the official threshold, and administrative agencies were required to record their reasons for refusal. An institution that calculated a risk had to explain its judgment even when it chose to take no action.
Support for the Life Protection Coalition did not decline after the war. Survivors from the three regions where actual disasters had occurred defended the Coalition. From then on, anyone opposing preemptive evacuation first had to explain to the residents of those three regions why they should have remained where they were. The result of ignoring risk was death. The result of excessive evacuation was mostly cost. The two outcomes were not remembered in the same way.
The Life Protection Coalition later changed its name and organizational form several times. The category of those to be protected expanded from residents who were presently alive to people in cryogenic sleep, personality copies, and restorable memory records. Tens of thousands of years later, this lineage led to the Alliance for the Duty of Preemptive Life Protection.
After the Third War, a new question was added to the galaxy’s disaster policy. It was no longer how high the probability of an accident was, but who would be responsible when a known risk was ignored.
