I believe you meant "bliss" in the topic title and not bless.
Should I, as a citizen, be concerned about what's happening to the world?
Do you only express concern about the situation in the world or actually take actions (no matter how small) to try and solve them?
If it's the former, then you could as well just maintain ignorance, but if you actually contribute to try to make the world better, then you are indirectly helping out someone and creating a healthier ecosystem.
World policies and activities affects everyone irrespective of whether you are aware of them, ignoring the problems would only make them larger until they would have to be noticed.
