The MBS is an interesting idea, but I've read some articles on it in myco forums that it would not work unless burial is done very shallow and in suitable areas, which is illegal and unlikely. Sorry i don't have a link to cite but i doubt the info is hard to find if you want to google it.
I'd love to see our culture embracedeath as the natural and beautiful thing that it is instead of living our lives in so much fear that we can't dialogue over it. Common modern burial practices are an extension of Euromaterialist disconnection from nature. The mindset that nature is to be overwhelmed, resisted and bulwarked against, in life and in death.
Why else do we give a F what happens to the solid container of our subtle body and minds, so much so that we protect our dead bodies from decomposition and scavenging?
I took a group to the animal jail recently and got to watch two vultures eat a deer carcass that had been presented to them. They almost seemed to ceremonially eat it, taking turns tearing the flesh and extending their long beaks into the body. While i don't like the fact that they were caged, it was a magnificent performance.
Embrace death, resist taxes.
