You can't sell a five-foot coffin. Okay, so that isn't entirely true. You can, it's just really hard. Everything we do is designed to limit the ecological impact of our choices. Our coffins are made from renewable and biodegradable resources, for example. So, it seems obvious to us that we also shouldn't use any more material than we need to. It sort of goes along with the backlash against Hummers, and the trend towards more fuel-friendly vehicles. So (be prepared, we're walking the line of morbid here), does a five foot person need to be buried in a seven foot coffin?
