Climate Change Could Affect Number of Baby Boys Born
According to a study conducted in Japan, global temperature changes could increase the number of miscarriages for male fetuses compared with female.
Studies and research done by researchers at the Institute of Health M&K Ako in Japan determined that the male gender of the human race could be affected by global climate change. The study explains how this might come to pass due to extreme climate changes on our planet.
According to studies, when there is an unusual temperature variation, the death of male fetuses increases, compared to that of female fetuses. A clear example of this was given by Dr. Misao Fukuda, leader of the investigation, who said that in Japan, the annual temperature has changed radically since 1970, and since then, fewer men than women were born in the country.
To conduct research and obtain these results, the study focused on two extreme weather events that led to the detailed analysis of birth rates. The first was the extreme summer of 2010 and abnormal winter in 2011. These two extreme climate changes recorded by the Japanese Meteorological Agency were used to obtain a balance with the data from the number of miscarriages officially registered in the database of Vital Statistics of Japan.
As a result of balances made on the basis of these two pieces of data, it was determined that during the extreme summer of 2010, there was a considerable increase in the number of miscarriages in this country, and nine months later, the number of male births decreased compared to the number of female births. The same data resulted from the research with respect to increased abnormal fetal deaths during the winter of 2011, also reducing the number of male births.
To affirm that climate change could influence the disappearance of males in the human race, the research was based on data from the studies revealed in Japan. Although these results are categorically obviously, they are not the first of their kind. In fact, in the past, similar studies have been carried out in Finland and New Zealand, though the research did not return a link that could determine that weather conditions were related to the gender of children born. In this regard, Misao Fukuda expressed that this result could have been cast out in those countries, since neither was exposed to such extreme temperatures as was Japan.
Globally, climate change is becoming increasingly apparent and its impact affects the environment and the living beings that inhabit it. Currently, it is difficult to say if the male gender will drastically decrease in the coming decades; global climate change is obviously different and affects some areas more than others. It is possible that this investigation might continue, particularly in countries where climate change has generated much impact. According to the statement made by Fukuda and his research, the most likely outcome is that these same results are cast out in places where there has been no extreme climate change in recent years.
