Freeze drying dead bodies may be a green alternative to burial and cremation, according to last week's New Scientist. Most of us would say we were concerned about pollution - but not many people realise that even after you die your dead body is seriously bad news for the environment and could carry on polluting it for another fifty years! Crematoria, for example, use 10 gallons of oil to reduce a body to ash! And in the process, poisonous chemicals like mercury from dental fillings are released into the atmosphere. Burial isn't much better for the environment - corpses can take over fifty years to decompose and when they do, they can release toxic chemicals that pollute the groundwater supply. But now a Swedish scientist has come up with a way to freeze-dry dead bodies and turn them into powdered fertiliser!
