More people are going green these days - recycling, buying less, driving cars with better gas mileage, and just being good to the earth. So it makes sense that these same people would not want to have a burial that causes pollution or involves toxic chemicals. The Natural Burial Company provides caskets made from recycled paper and biodegradable materials, and their website has a wealth of information about green funerals, natural burials, and related resources. They even have a link to a local company, Mourning Dove Studio, that makes one-of-a-kind caskets, urns and shrouds.
If you want your conservation efforts to continue even after you are gone, you may want to get in touch with these companies when you are planning for the end of life, and also make sure that your family knows your wishes.
