Read an article about death practices in a special issue of 'New Scientist' today. Cremation is not very environmentally friendly. A better option is woodland burial in a biodegradable coffin. I America, it is legal to compost human bodies, and they can be wrapped in a shroud impregnated with fungal spores, which will convert the body to compost. I think I'd like a woodland burial - but not for a good few years yet, I hope.
