What Happens in a World of Men, Without Enough Woman?

An article I just read tells me: still-growing international predilection for sex-selective abortion is by now evident in the demographic contours of dozens of countries around the globe — and it is sufficiently severe that it has come to alter the overall sex ratio at birth of the entire planet, resulting in millions upon millions of new “missing baby girls” each year. In terms of its sheer toll in human numbers, sex-selective abortion has assumed a scale tantamount to a global war against baby girls.

This article from the New Atlantis says the phenomenon is prevalent all around the world. I wonder what will happen when we have a large part of the world over populated with young men with all their natural aggression and not enough young women, who at the same age are looking to find husband and start families. [I speak biologically, not culturally]. Does this promise a continuation of war which has always levened the balance by killing off man of the young men? Does it suggest some very different role being forced upon the women?

As soon as we start tinkering with the balance of mother nature, be it human or the introduction of kudzu bad things happen. Now I have something else to worry about.
