Cremation is a way of using irreplaceable fossil fuels to turn perfectly good organic fertiliser into greenhouse gases.
Burial usually involves toxic embalming chemicals that interrupt the cycle of nature. In many places, shortage of space means that you get supplanted after a number of years anyway.
A wonderful group has developed a practical alternative.
For many years now, I’ve explained my preferred method for getting rid of my body when I no longer have a use for it: put it in a biodegradable bag (paper is fine), and bury it, not too deep. Plant a walnut tree on top. Then, my descendants can meet once a year to gather Bob’s nuts.
Recompose have developed a technique of accelerated composting that converts an average-sized human body into a couple of wheelbarrows-full of rich soil.
