Afterlife or not the question is where are we going to bury all the People? If as pointed out the reuse of a plot is around 100 years and as I previously stated the number of deceased is around 1500/day then burial has either got to be prohibitively expensive or like organ donation the conversation about cremation has to be brought to the fore.

One way or another just turning a small area of land over to burial is delaying the inevitable so in a years time when it is full where next?

Organ donation will provide the means of an Afterlife and the ashes left can fertilise plants/trees? Also given the ground conditions is there not a danger of bodies contaminating the water table?..I don't know just thought?
