In the early 1990s I read about the big problem with cheap, portable sonograms making their way out to the Chinese provinces: namely, parents were aborting female babies the moment they got the news about their children’s gender, because they wanted sons. It didn’t take much advance thinking to realize that this would become a major problem.
According to AP, China’s now looking at 30 million more marriage-aged men than women, which won’t be healthy for anyone.
