I would like to know how did they came to the conclusion that the world problems is caused by nature and not other selfish people. Politicians who didn't allow me to my country's university because of my religious beliefs made this choice not because "the nature" forced them, or they somehow lacked free will. They may blame our flawed natures like greed but I would argue that we can choose not to listen to our emotions and desires. I can shallow my anger, and silence my pride which makes me an entity separate from it's emotions. People can also change their mind if they choose, both in a positive and negative way.
