Europe is poor and Europe can't afford condoms or birth control. Serbia, Russia, and Albania are examples of poor Europeans who can't control their breeding habits. Africa was the richest continent until the Europeans started to steal all the resources.
Africans are poor and they don't really know much about how this whole "prevention" thing works. And asia already has too many people(especially in china) so they are more ristrict about birth control, getting pregnant and stuff. And europe?
Well... There is too many old people, who require health care and money to live, but cant work anymore. So they need more young people(who keep moving out to america pr different countries in europe, or don't neccesarily want to have children...).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
