Many people prefer cremation because they've heard about environmental issues with contemporary American burials.
Many American burials are problematic for the environment. Over 180,544,000 pounds of steel and 5,400,000 pounds of copper and bronze from metal caskets are put into the ground each year in American cemeteries. (1)
Embalming is terrible for the environment: More than 120 gallons of untreated "funeral waste" goes directly into the sink per embalming, meaning 827,060 gallons of embalming fluid, including carcinogenic formaldehyde (2) goes into the ground each year.
Why should we waste precious land on the dead?
Cremation seems like an eco-friendly land-saving alternative, and is often promoted as such. With a little research, however, the facts come to light. They are discussed in detail on this site.
Cremation uses up an extremely high amount of fossil fuels
Cremation releases a disturbing amount of toxins (including mercury) into the air
Burials use up a shockingly small amount of land, and there is plenty of land available – in fact, if all Americans were buried, it would take 10,000 years to use only 1% of America's land mass, and presumably few, if any, cemeteries would survive that long! Complaining about wasting space on graveyards is like a herd of buffaloes in a huge open plain complaining about the space that a family of mice take up!The green movement is not in favor of cremation, rather it promotes "green burial" without embalming or metal caskets
Jewish tradition forbids metal caskets and embalming making Jewish burials a model of eco-consciousness
In sum, American burials are bad for the environment, but this is almost completely due to metal caskets and embalming, both of which are against Jewish tradition. Cremation's environmental hazards are much worse.
Cremation is not the choice of environmentalists around the world — burial (with no embalming or metal caskets) is.
