Have you ever thought of continuing life on earth after death? Perhaps as part of a tree? Although there is a wide range of beliefs on afterlife, one thing is certain: your body is staying here on Earth

Cremation

One of the popular burial method is cremation . Statistics has shown that in 2004, America’s national cremation rate is 30.88% and continues to rise year by year. Cremated human remains consist mostly of calcium phosphate, along with minor minerals such as sodium and potassium. Other elements such as carbon and sulphur are released as gases during burning, although a small amount of carbon does remain as carbonate.

How does cremated human remains become part of trees?

There are several options on what to do with human ashes, such as keeping it at home, burying it, and sprinkling it over the ocean or land. Recently, industrial designers, Martin Azua and Gerard Moline, have developed a creative, eco-friendly way to dispose cremated human remains. They have designed a biodegradable urn made from coconut shells, compacted peat, and cellulose. This is also known as the Bios Urn. Ashes will be placed inside the urn as well as a seed of a tree. The urn will then be buried. Calcium phosphate is an excellent fertilizer and since human remains are a good source of those, it will fertilize the seed which will germinate and grow into a tree. Best part is, you get to decide what type of tree or plant you want to become part of.

Although trees help the environment by taking in carbon dioxide for photosynthesis, the cremation process also releases a bunch of carbon dioxide. Depending on the size of the body, cremating one corpse can require two to three hours in a furnace generating more than 1,800°F of heat. Environment analysts have calculated that this energy releases 573 pounds of carbon dioxide into the air. Environmentalists have been trying hard figuring out ways to reduce carbon footprint, so imagine the amount of carbon dioxide released each year from just cremation, is it worth it? Would you want to be buried in the Bios Urn?
