Big gender imbalance in some countries. China will soon have more than 24 million surplus males and globally this figure will be 160 million. All down to a preference for males. The causes are unclear. Even before scans revealed the gender of the unborn, baby girls were being murdered in places like China and India, often by the horrific practice of throwing them down a well. The West also has seen increased female infanticide.
It could lead to wars. Both sexes lose out with single men being marginalised and women being over protected.
Psychologically it can even lead to misogyny.
Or is this the best and only real way to curb population growth?
