angola: Down and out in oil-rich Angola

Gracelino is dressed in dirty rags. He extends his skinny arm into his pocket and produces a small plastic bottle filled with a see-through liquid. This is gasoline which he bought for $1 at a market, and there is enough here to last him for up to three days. "You put the petrol onto a piece of cloth and sniff it. It makes me feel high, but I know it's no good for me and so I'm going to stop doing it," says the 15-year-old. Gracelino is one of many street children who are addicted to a by-product of the very substance that makes Angola so rich in one of the world's most sought-after resources.
