but, ok, lets begin with new york city, i know the city has 14 million people
so after 60 years, the city has to have 10 million - 13 million graves available to accomodate so many dead people, where the hell are they gonna get so many rooms to make cemeteries???
same situation apply to all over the world, 60 yrs later we need at least 5 billion grave yards, where the hell are we gonna get the land? and, further down the road, will earth over run by cemeteries after 200 years? are we gonna bury people on the moon or mars? thats really heavan you know?
