An uncertain future for a planet full of men, experts say

At a time when the world population crosses the barrier of 7,000 million people, experts fear that the gender imbalance favoring the emergence of unstable "country singles" in fierce competition to find a wife.

The exact consequences of what the French demographer Christophe Guilmoto called the "masculinization alarming" in countries like India or China, due to selective abortions are still uncertain.

Many experts believe, however, that in fifty years the shortage of women will have an impact on society similar to the warming climate, an invisible but very real phenomenon.

After these warnings are hidden irrefutable statistics.

Nature offers unchanged figures are born between 104 and 106 boys per 100 girls, and the slightest modification of this ratio can only be explained by abnormal factors. 

In India and Vietnam, the figure is about 112 boys per 100 girls. In China, the proportion rises to almost 120 by 100, when it is not 130 boys per 100 girls in some regions.

The worst thing is that this trend extends: in Azerbaijan, Georgia, Armenia, the relationship between the births of more than 115 boys per 100 girls. In Serbia and Bosnia contato the same phenomenon.

 The global awareness about going back to 1990 when an Indian Nobel laureate, economist Amartya Sen, published an article with a blunt title: "More than 100 million women have disappeared."

Demographers estimate that this figure is now above 160 million and is the result of the traditional son preference, falling fertility and, above all, inexpensive ultrasound that allow abortion when it comes to a girl. 

Although the proportion of births to return to normal in India and China over the next ten years, Guilmoto estimated that in both countries, the marriage will be for several decades a headache for men.

"Not only do these men have to marry at an older age, but who are at risk of being single in countries where almost everyone managed to find a woman," he says. 

Some believe that this new context might increase polyandry (a woman with multiple husbands) and sex tourism, while others provide catastrophic scenarios in which sexual predation, violence and conflict would be the new social norms.

A few years ago, political scientists Valerie Hudson and Andrea den Boer came to write that Asian countries mostly populated by men posed a threat to the West. 

According to them, "Companies with strong male-female ratio can only be governed by authoritarian regimes capable of suppressing violence at home and exporting it abroad through colonization or war."

Mara Hvistendahl, a reporter for Science magazine and author of a recent essay entitled "Unnatural Selection", argues that the risk of large-scale war is unlikely, especially remembering that India is a democracy.

 Admits that "historically, societies where the number of men than to women are not pleasant to live," evoking the risks of instability and even violence.

The services of the UN have warned of a correlation between the lack of women and an increase of sex trafficking or migration of populations in search of marriage. Solutions to the problem at the moment are not abundant.

According Guilmoto, the priority now is to ensure that the problem is public knowledge, and not only in emerging countries. "In Eastern Europe, people have no idea what is going on," he says.
