I'm an atheist and I do not understand why bury people in the huge areas which is not always enough if you can solve the problem at the expense of the cremation. All big cities are constantly experiencing problems with places of burial.
This is now a business. Imagine how many people will be ruined if you stop using the cemetery for burial.
In my country, the cemetery is a very lucrative criminal business. If people are cremated, they will still find a way to make money on human misery. I am sure that the method of burial, the cost of the procedure will only increase.
