I understand the sentiment, and I'm also careful about how much news I consume, but there's a fine line between this and being privileged to be able to afford to skip news because those suffering aren't your family.
In a less extreme example, if a big project came into your neighborhood to destroy all the houses on your street to build a highway, I'm sure that suddenly this news would make you want to get involved politically to advocate against the destruction of it. But when that happened in the other neighborhood and you didn't care to even write an email to your local politician to oppose it because you didn't know about it, other families suffered.
It's a fine line.. I've seen my parents watch news 3 times a day (lunch, dinner, and late-evening news) and it was definitely not healthy and did not make them better citizen either. I don't have a perfect answer.
