Again about population failing to replace themselves when they industrialise and "Civilise". Well, this is not neccessarily true. When I was a child, the Chinese had a population that was generally reckoned to be about 500 million. before 2000 they had so many babies that it was a cause for worry and the authorities imposed a so-called "One ChildPolicy". (The population was then said to be about one Billion!) What was it caused this increase in the population? To me, (No expert on such matters.) it looked like people could, suddenly, afford to have and bring up children and feed them and so, that is what they did.
In Europe and the US, after WW2, there was a period unti the 1970s(?) when there was what was called a "Baby Boom". which coincided with a period when a man's wage was enough to keep a family. Later, when it became neccessary to have two wages to keep a family, the population stopped expanding. Causal or coincidental? I don't know, but it seems to me, there could be a cause & effect connection.
I have also read that the sperm count of European males has been falling since the 1920s. I have never seen figures for other countries. I have seen recently statements that the (RDI?)reccommended daily intake of vitamin D is set far too low, and that majority of patients coming to one North American Clinic are found to have very low levels of vitamin D compared to people who work out of doors. Might this be related to very low levels of reproduction/fertility?
