As cremation trends toward the norm across the United States, critics come out of the chemically-untreated woodwork. Cremation is an unsafe practice, they say. The act of cremation emits dangerous toxins into the environment, and consumes huge quantities of energy simply to turn one body into ashes. While some of these complaints have a small nugget of truth, the misrepresentation of information is striking. Experts claim that cremation and use of biodegradable urns are actually far more environmentally-friendly than a traditional burial, particularly when modern technologies and new approaches are used.
