The first picture won the Pulitzer prize (sometime back in the 90's???) As far as I know, the theme of the picture is s.t. like "waiting for food". The child is crawling towards the UN office where they distribute food (not shown in the picture of course). And the vulture is waiting for the kid to die (remember it does not eat alive human flesh) so that it can have something to eat. I am unaware of the photographer's personal life though.
