Death is a messy business. In America alone, 1.6 million tonnes of cement and over 870,000 gallons of embalming fluid - commonly containing formaldehyde - are buried along with 2.5 million caskets every year.

“What you have here is a landfill … a toxic landfill,” says Glen Ayers of the Green Burial Committee as he looks around a traditional graveyard in Massachusetts.

Proponents of natural burial want to reduce the pollution and resource waste associated with funerals, which also includes burying masses of hardwood and steel.

One solution is to use eco-friendly biodegradable coffins made out of cardboard or even banana leaves. Campaigners also hope to increase the number of natural burial sites, where plots blend in with the natural surroundings. There are currently fewer than 40 in the US.

Russell Beard travels to Massachusetts, US, to meet the people hoping to bid the world a green goodbye.
