You can smell the refuse dumps of Cairo from miles around - piles of rags, bones, tins and paper await collection, while the rotting foodstuff is gorged by thousands of pigs, who rootle around the dumps.

Mike Hopwood reports on the dehumanising effect of life on the rubbish dumps and asks what can be done.
