Why does the Bishop think the newest natural burial will become popular?

Australia’s newest natural burial site sits in a quiet corner at Kemps Creek, on the edge of Sydney. There are no gravestones or grand mausoleums—just a patch of bare grass surrounded by a simple wooden fence. Those laid to rest here will be buried in biodegradable coffins.
    Julian Porteous, the auxiliary Roman Catholic Bishop of Sydney, thinks it will become a popular option. "I think people will have a greater sense of their unity with creation, " he said. "From dust we have come, to dust we shall return. In no way would this diminish all those very important human dimensions to the experience of death. There would still be in the Catholic tradition a full funeral Mass and the chance for the family to come together to pray."
    Graves at the Kemps Creek eco site can be leased for about $ 2, 200 and are recycled. Tenure is limited to 30 years, and if the license is not renewed, then that plot is used again by someone else.
