Knowing two people who are bipolar, I would have to say that the condition itself is nature (genetic), but how well a person copes with it and the people around them can be helped by the nurture aspect. Were they diagnosed early enough to get help? Does their family know, understand and accept the condition and do their best to help?
I believe it would depend there are variations on both arguments. Generally speaking nature argument would be that due to genetics or other predispositions bipolarism would be present no matter if the child has interventions, is adopted by anouther family etc. It basically is there or not and no outside factors cause it or stop it. Nuture argument would state that the environment people, community, food etc would impact and determine if someone would become bipolar if a certain combination of triggers where in the individuals life.
In the same regard in the nurture theory interventions and even possibly stopping bipolarism would be possible. While nurture family etc has no real part in it besides perhaps changing intensity of ups and downs once the person is concieved and genetic makeup is determined before birth.
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.
