Take an empty Coca-Cola can laying around in your favorite war-zone scenario (cans are available worldwide), polish the lens-formed aluminum bottom with some tooth-paste you also found laying around anywhere, use your thumb and the paste until the concave bottom shines and it reflect things around you. Clean with toilet paper.
Take the same toilet paper sheets, and burn a hole in it using the sunlight reflecting and concentrating in a tiny point, off the shiny half-moon shaped bottom of the Cola can.
The paper will start to burn, light a campfire with it, and maintain that during the lonely nights.
In Alaska, you could fill the Cola can-bottom with water, wait till it freezes, and you'll have a lens which will function as a fine burning glass in sunlight.
For the real geeks:
Demolish a DVD writer disk housing, find the blue laser inside, connect it to a battery and use that to burn papers. Will operate for a very long time. Years.
For the more simple mind orientated persons:
Any reading glasses in spectacles found on dead bodies, or borrowed from living ones in a disaster area, will function perfectly as burning glasses in sunlight.
Don't try this in the dark...
Another easy to find article: throw-away electric lighters.
Must be billions laying around worldwide by now. Full perhaps, but certainly empty.
Don't mind if they have no gas in them anymore, demolish them and take out the piezo-electric lighter part, and use it to make small but powerful sparks, which you use to light fire into small bundles of dried moss.
Moss can be found in any forest.
The piezo-electric part will last many years.
Don't mind the electric shocks you first will receive, you'll find ways to insulate this useful thingy.
