It's about time people opted for cremation. It's seems crazy that we keep using land for burials when it is so limited. Either that or burial is for a limited time then then like the Chinese thd bones are put in a jar and would be more efficient to store/ display etc.
In the past I helped tend two cemeteries and whilst there were some visitors that regularly tended their loved ones the vast majority were left abandoned.

Given also the number of lonely old people who rarely see any relatives ask the proprietor of zn old age care home. Then why take up land space? Seems simple if the UK will have a population of 70 million where are we going to put them All?
