How did it come to this?

摘要

On a beach near Chittagong, Bangladesh, teams of men clamber over what used to be an oil tanker, ripping it apart with little more than a cutting torch and their bare hands. Working in oppressive heat amid toxic fumes, this is one of the most dangerous jobs in the world - and one of the most polluting. Each ship contains some 50,000 tonnes of metal, toxic chemicals and asbestos. The last place you'd want it to be dismantled is on a beach in the developing world, but this is exactly what's in store for this tanker and thousands of others.
