Third Arc - Earth's problems follow them

I don't have the concentration to write it tonight, but issues will
arise aboard the arks, and some examples follow of how this might play
out.

Abortion - legalized or no?  On some arks, yes.  The Federal
and state governments no longer have the financial leverage they did.

Some will argue on banning abortion on an ark-wide basis for a given
ark (like Houston).  They will say that increasing the human
population will be necessary in the given months, in addition to all
the usual reasons for taking such a position.

Their opponents will argue that in a limited ecosystem, giving birth to
babies will only increase life-support burdens past a manageable level.

Some people will say that teen abstinence needs to be rigidly
enforced.  Others will say this is highly improbable aboard a
closed starship in a tense situation, and that people who have little
else to do will procreate.

The notion of forced sterilization, or child-registration programs to
control population growth, will be hotly debated.
