That statement doesn't preclude some political activity if you consider it to be something that you can actually "impact and improve", in the author's words. Of course I can only speculate about the author's original intent, but I think I agree insofar that most daily news out there is irrelevant for most individuals. Even if you have a political cause you are interested in, you have limited time and energy, so it might be better to just stay informed in those areas that concern you and ignore the rest of the daily news.
You can't fix the world as an individual, so it's pointless to concern yourself with things you can't impact. Of course that still means that everyone should probably find a little thing where they can try to make a change.
