Most important thing bothering the World today???

According to me, the one thing that bothers the most the world over is terrorism.. It has grown to such a large extent that it has instilled fear in almost everybody's mind..

I think what bothers most peole today is simply the lack of a sense of purpose. We live in a very materialistic world that puts a lot of premium on things physical and fleeting. We think we are happy because we get to have the things we want want. At the end of the day when we analyze things, we usually end up thinking what then? So what? What did I really accomplish? Have I really made a difference? And to quote a famous song, we ask "What's it all about (Alfie)?"
