Will you choose an elaborate Victorian-style headstone, or do you prefer a “green” burial, with only a GPS tracking signal indicating your location? Or you may elect to purchase a Bios Urn – a 100 per cent biodegradable capsule you plant in the ground with cremated ashes and a seed of your choice which will one day grow into a tree. Issues of mortality and access to burial space are not typically dinner party conversations or at the top of government agendas.
