Grave Matters

From a book on eco-friendly burials, via Marginal Revolution:

Over time, the typical ten-acre swatch of cemetery ground, for example, contains enough coffin wood to construct more than forty houses, nine hundred-plus tons of casket steel, and another twenty thousand tons of vault concrete. To that add a volume of formallin sufficient to fill a small backyard swimming pool and untold gallons of pesticide and weed killer to keep the gravehard preternaturally green.
