The world now is different to the old world .In the old, the humans cant communicate with each others and appear its large world and we cant imaginary this world .  After the development in the Internet and computer technology  and improve in the transport technology ,the  world became small and small and now its like the small town. Step by step the borders between the countries are neglected .May be after some years or decades the world become only one country and  one leader which judge between the humans in justice and all these human life in happy and well........
