I wish there were an 800 number at the end of the newspaper that you could call to do something about the horrific things you've just read.
I would call on Sunday. I imagine it would go something like this:
"The New York Times how-to-make-the-world-better-hotline. May I help you?"
"Yes, I'm calling because I feel really bad about all the terrible things in the world that I just read in your newspaper."
