Human smuggling is now said to have an annual turnover of over $7 billion — more than revenue from smuggling drugs. Caroline Moorehead's important new book looks at 'human cargo' from Afghanistan, Liberia, Palestine and many other places. She has visited war zones, camps, prisons — and the black Dinka families from the Sudan who were re-settled north of the Arctic Circle in Finland.

She follows the fate of 57 young member of the Mandingo tribe, who fled ethnic cleansing and ended up happily in America via Egypt. She is shown the graves in Sicily of drowned boat people, and examines the fence that has been built across Texas and into the sea to keep migrants out of America. She has interviewed emigration officials in Australia and members of the United Nations High Commission for Refugees in Geneva. Is there a valid distinction between 'good' asylum seekers and 'bad' economic migrants?

What happens to those whose applications are turned down? The difficult questions are asked, the horrible issues faced. But, above all, Human Cargo celebrates the courage, cheerfulness and will to survive of ordinary human beings
