Now, it has always been my assumption that,
being reptilian and based on the fact that they had a birth rate that
represented a true strategic advantage, Krogan gave birth in large clutches
somehow. Each birth representing possibly dozens or more Krogan. At
the very least each clutch would have to be 3 or 4 or it wouldn't have
represented the overwhelming strategic advantage that it was. In my
opinion I place the number in the hundreds due to the significance that it is
given in the cannon. For example Wrex notes that 1 in 1000 survive and
Mordin states that they stabilized Krogan population at pre-industrial
levels. A stabilized population has a growth rate of 0%. This means
each pair of Krogan has to give birth to 2 children plus some number to make up
for those who either choose not to procreate or who die before being able to do
so. Lets say that this number is 2.1 (unlikely given their constant
fighting, but humor me), that means that each pair of krogan has to give birth
to 2100 children just to have their 2.1 viable children necessary to keep their
population growth from being negative.
Why is this important? If the Krogan had a reproductive system that was
more like ours where we generally only have one child per pregnancy then they
could have potentially fought massive overpopulation by simply not having sex
or using some form of birth control. Now, if each birth represents 5
Krogan (a VERY low estimate simply for the sake of argument) then you have
a 250% growth rate. Having 100 children per clutch gives a 5000% birth
rate. This is assuming that each Krogan has a single mate, gives birth
only once, and there are no deaths prior to the new Krogan mating. There
is no easy way to reduce this number. If you want one child you have to
have around 5. So unless they practice infanticide (which is no different
than the genophage currently is and could potentially be much worse) they have
an unsustainable population. There is no way to fight it, no abstinence
or birth control will work. The only solution would be to limit who could
procreate. Does anyone see a race like the Krogan going for that?
So, unless anyone has an argument that explains how anyone would have been able
to peacefully coexist with a race capable population growth greater than exponential
(each generation doubles) that lives for centuries, please let me know. You don't even have to consider whether they are warlike or not, just the fact that they eat, breathe, and take up space is enough.
EDIT:
I had to add this because I thought it applied to this situation so well. I found this little story on the wikipedia page for exponential growth in case anyone was curious.
"French children are told a story in which they imagine having a pond with water lily
leaves floating on the surface. The lily population doubles in size
every day and if left unchecked will smother the pond in 30 days,
killing all the other living things in the water. Day after day the
plant seems small and so it is decided to leave it to grow until it
half-covers the pond, before cutting it back. They are then asked, on
what day that will occur. This is revealed to be the 29th day, and then
there will be just one day to save the pond. (From Meadows et al. 1972,
p. 29 via Porritt 2005)"
