LElstow VTP Annotation

The photo does not actually convey a feeling of overriding pollution - in fact there are gaps in the traffic, indicating that it is not incessant.  But with the caption this makes the reader/viewer realise how much of an every-day scene this is potentially and that this could be replicated in cities all over the world.  It shows how local residents who are economically vulnerable and live precarious lives are more or less forced to submit themselves bodily to pollution in order to maintain their crafts lives.
