Marriage isn't biological, it's a social construct. Birth control and abortion are also not natural in that sense but human-made. Human evolution is biology btw, but evolution doesn't necessarily mean that humans have to reproduce like rabbits until everyone starves to death from overpopulation. There is a reason that the birth rate is generally lower the wealthier and better educated a population is.
