Having 2 children does not balance the population.
It increases the population by a lot!
Consider a 20yo couple having 2 babies.
20 years later, those 2 have two children each.
20 years later those 4 have two children each.
20 years later those 8 have two children each.
Meanwhile the original couple are STILL alive (damn them!) but in a mere 60 years have 16 EXTRA people in the world!
Now multiple that by the amount of people having babies and you then get BILLIONS extra every few decades!
I happen to love maths.
I actually didn't think you'd get it.
Having 2 children is not balancing since each child could then have 2 babies each.
So the 'population' grows. But anyway whatever.
Its actually the Adam and Eve type of story (which didn't happen by the way)
Why do women have babies?

Reducing population, means having ONE child only.

It takes a mommy and a daddy to make a baby. Maybe you should take a little more time to think about the math behind that.

You're not taking into consideration the birthrate, death rate, and infertility rate.
Starvation, disease, infertility, abstinence, and war are factors in population growth.
Zero population is maintained by 2.8 children/couple. Fact.
You're way off.

Of course these other factors are present. Nonetheless they are heavily OUTWEIGHED by the exponential rate of the multipliers
