Your most recent contribution to this thread was when you said:
They're in the second development stage, which means it's socially encouraged to have a lot of kids. The same was true of the US and Europe a century ago.
With regards to the "second development stage" Europe witnessed "100 years ago", I don't see how you can classify what is happening in Africa with anything that has ever happened in Europe. Moreover, I have never heard of a case where African society or individual African governments have ever encouraged increased births per capita. But this is irrelevant, because the single defining aspect of, "Europe 100 years ago" was its industrial revolution, along with its noticable increase in standards of living and life expectancy. Africa's exploding population has less to do with increased life expectancy and more to do with increased breeding. See the above life expectancy graph for proof of this. Life expectancy in Africa has plummetted over the last 20 years, all the while, the population has markedly increased. This leaves only one possible explanation: increased births per capita.
With the exception of South Africa and Egypt, it is arguable whether most of Africa has even reached a primitive level of industrialization. By insinuating that Africa is similar to European levels of progress 100 years ago, you are saying that in 100 years, Africa will be as developed as Europe. I wouldn't bet on that.
Because you're idiotically mistaking sexual promiscuousness for having a large family.
Like I said before, when the majority of African kids (as witnessed by the staggering number of orphans in Africa) do not know their father, then "by civilized classification", those kids are most likely the result of an act of sexual promiscuity. Or maybe having 'one nighters' in Africa is not promiscuous, if that is the angle you were going to take... I'm sure African sexual promiscuity is more loosely defined than what westerners are used to, and I bet kids born to dead beat, absent fathers is quite acceptable and normal in Africa.
