Suicide is not one of the main causes of death around the world. http://www.who.int/mediacentre/factsheets/fs310/en/
It isn't natural for people to kill themselves, most people don't. I haven't because I don't want to, it's that simple. I believe in the right to die, I do not think suicide is immoral. If I wanted to die, I would first seek medical treatment incase the desire was caused by some physical or mental illness. If I found myself to be healthy and of sound mind, or unhealthy and untreatable, and still wanted to die after that I would find a place where I could end my life in peace with minimal interference from others and my life would end. But I don't have any desire to die so it's not really relevant.
