What is the life?

I am confused. The life is really inetresting and challenging thing that can happen with everyone. The life is not fair. Many people on the Earth are poor, some even don't have their own house or the place where to stay at night. Some nations do not have water or even something worse. But in the middle of all of it usually apears some politicals events. They tell us that some other nations are different and that they are a danger. But it is not true. We all want the one thing is peace. That to grow up our children, that to help other people, that to make the life better.
