I find "why" to be a useless question. Ninety-five percent of the time, I have no way of knowing or finding out. Even if I did know the why, it doesn't change the "what" I need to do about it (if anything) and it doesn't give me the "how" I'm supposed to do whatever that might be.

I ask myself these questions:
1. Does this have impact on my daily life?
2. Do I have any control over this?
3. Can I do something that will either make the most of this or mitigate the potential harm?

If the answer to these three questions is "no", I surrender it to God and move on.
