Hot climate produces baby girls


In “Hot climate produces baby girls” BBC News report that the birth rates of girls in the tropics are higher than in other parts of the world. They base on the birth place. People who live by the equator have more girls than boys. This causes a variety of climate that may effect on miscarriage rates and sperm quality. In addition, from the research, “the female foetus is less fragile than the male foetus, which is more prone to the effects of the environment on pregnant women.” However, it is difficult to draw conclusion because the other factors can also change the birth rate such as the different of culture, society and economy in each region.

Which factor do you think that most effects on the birth rates; the different climate, culture, society or economy? Why?
