This is a good point, but the average person is unlikely to hear about a skirmish on a different continent, and then know they should start stocking up on tinned food and bottled water. The problem is with the volume of information. It's impossible to take all of it in, so you need to pick and choose, and stay within your own limits. Some people might have the capacity read a whole newspaper's worth a day, others can only manage the local headlines.
