Peter Hitchens, reporter, wrote this article in the Daily Mail [UK] -- the article details not only the shortage of girls in the population, due to China's "one child per family" policy, but it also goes in to detail re: China's increasing problem of child theft.
The article starts:
"In the cruel old China, baby girls were often left to die in the gutters. In the cruel modern China, they are aborted by the tens of millions, using all the latest technology.
There is an ugly new word for this mass slaughter: gendercide."
The article states that China's one-child-policy started officially in 1979.
However, I personally remember that in at least parts of China as early as 1974, the government was encouraging/enforcing this. I remember that in Fall of 1974 when I was a college Freshman, writing an essay about the policy for an English class I was taking at the time. IT was the first I'd heard of it.
Unfortunately, in large parts of India, parents are also chosing gendercide. Not through goverment threats, but of their own volition. Quite some time ago, I'd seen a TV documentary which covered the phemomenon. Sleezy abortion doctors in their Mercedes Benz cars, pulling out their scanners in poor neighborhoods for relatively quite handsome fees to tell parents what sex the baby was -- then parents aborting if it was a girl.
There is also this article which is worth a read -- it goes into more details about India and China. [And it also confirms my 1974 date as to when the use of amniocentisis began to be used for this purpose of sex selection and gendercide.]
And there is also a recent article from the Economist, which points out that often the WORST gender imblance is in the WEALTHY parts of the country.
