Ok do she isn't a parent but refers to other people's 'lifestyle choices'. Well having children is certainly a choice for some in developed countries yes, but not so much in developing and third world regions where access to adequate contraception is limited or absent.
Humans have a strong biological drive -as do all species - to procreate. Males have a strong urge to spread their seed so to speak. Females to raise young. This often results in an 'unplanned' child. Lifestyle choice might apply to wealthier countries, but certainly not across the board.
