There is a looming problem in many parts of the world over what to do with dead bodies, as pressure on burial space intensifies.
The industrial revolution, in the 18th and 19th Centuries, saw a mass migration from small villages and towns to cities.
Previously, most people had lived in rural locations and would be buried in the local church’s graveyard.
But with a growing urban population, the authorities in Victorian Britain built large cemeteries, often on the outskirts of cities.
