No Generation Ship would launch without figuring out the population thing in advance
.
Indeed. The leaders would always make sure things are set up correctly ahead of time.
They will make sure that nobody is so dumb that they build many multitudes
of houses in an unsafe area that is beset by many problems - like being a firetrap.
And they will make sure that the reservoirs are filled and functional.
And the fire hydrants actually work.
We will always be lucky enough to have these things. Right?
So our leaders would certainly be up to the task of shepherding lots of
folks to new planet, right?
