Climate change alter the ratio of male & female newborns

Global warming will have a variety of effects on our planet, yet it may also directly impact our human biology, research suggests. Climate change could alter the proportion of male and female newborns.

Climate change alter the ratio of male & female newborns
With more boys born in places where temperatures rise and fewer boys born in places with other environmental changes, such as drought or wildfire caused by global warming.
recent study in Japan found a link between temperature fluctuations and a lower male-to-female sex ratio at birth, with conceptions of boys especially vulnerable to external stress factors, wrote Dr. Misao Fukuda, lead study author and founder of the M&K Health Institute in Hyogo.

Fukuda theorized that the vulnerability of Y-bearing sperm cells, male embryos and/or make fetuses to stress is why ‘subtle significant changes in sex rations’ occur.

Catalano said that this is a result of the fact that a male infant is a ‘relatively frail organism’. “For every society, for every year, the human being most likely to die [prematurely] is male infants. And that’s true for every society that we have data for.”

Samuli Helle, a senior researcher in the Section of Ecology, Department of Biology at the University of Turku in Finland, also found that “warmer temperatures bring sons.”

Humans are incredibly adaptable, we got through the Great Ice Age, so he has no fears that we will adapt to climate change. Climate change is going to change the characteristics of the population in ways that maybe can’t be anticipated.
Fukuda believes that any potential effects of climate change on the newborn ratio “may not be uniform” around the globe. It may depend on different environmental factors of each place.

Though all the reasons for this male-to-female ratio change are not understood, but scientists believe that boys are biologically weaker and more susceptible to diseases and premature death, leaving the possibility for more male-to-female disparity wide open in the age of climate change.
