I know that cremation grew out paganism. I know that for many years the Church objected to it. But I find it less objectionable than many of our current standard-American embalming/burial practices. That said, I don't want to be cremated, and I don't intend to cremate anybody for whom I'm making funeral arrangements.
There is "green cemetery" space in Waukesha. Although the cost is higher, there is also an option for "natural burial" in the regular parts of the cemetery, where a grave-marker can be placed. For theological reasons, I think making note of the body's spot is important too, so ideally, I'm not keen on the idea of burying people "somewhere" on a prairie.
The part of "natural burial" that troubles me most is the people that the family would be working with. If their worldview and their theological perspective is the complete opposite of that of the grieving family, would that cause problems? And if so, which would be easier to take: their weirdness or going along with Standard Procedure?
