I absolutely agree with your points, but at the same time we can only worry about a fixed amount of things, and stress is very unhealthy — so from a purely mental well-being point of view, constantly thinking of all the bad things around the globe is not a good thing to do. Especially when we have a hard time actually effecting the given thing.

I don’t know what should be the solution, perhaps it would be the task of elected politicians to try to fix the problems in place of the population, even in other countries? Which do happen, but it should be much more prevalent.
