Now you can say, "I'll go green over my dead body!" and not have to worry about people thinking you've lost it. Designer Martin Azua's Bios Urn pries eco-friendliness from your cold dead hands, by using cremains to help nourish a tree seed. The urn is made from cellulose, coconut fiber, and peat, and it already contains a seed of your choosing — just add ashes and bury to become your own personal memorial park.
