Burnt, buried or frozen and turned to powder are some of the options for dealing with the remains of a loved one whose last wishes include lessening death's environmental impact.
Our demise can have a big environmental impact. Around three quarters of people in the United Kingdom alone are cremated after they die but cremation uses about the same amount of domestic energy as a person uses in a month.
Globally, cremation emits over 6.8 million metric tons of carbon dioxide every year, accounting for around 0.02 percent of world carbon dioxide emissions, experts estimate.
It also causes mercury pollution when tooth fillings are vaporized. Currently, up to 16 percent of all mercury emitted in the United Kingdom comes from crematoria, which could rise to 25 percent by 2020 without any action, according to government figures.
