We have a huge cemetery near us in North london, created when our area was still fields to serve as an out-of-town burial site for Islington (more central). It is a very humbling place to stroll around, particularly taking in the huge and elaborate Victorian monuments to men who were clearly big wheels in their own time which are now unvisited for generations and, in many cases, already crumbling and eroded to near illegibility by acid rain.

And death shall have no dominion.

Dead men naked they shall be one

With the man in the wind and the west moon;

When their bones are picked clean and the clean bones gone,

They shall have stars at elbow and foot;

...

Dylan Thomas 1933

I prefer to think of myself as a rational, scientific-thinking human. Nevertheless, I don’t think I could setup a tent and sleep in a cemetery, which calls into question just how rational I am.

Cremate

Cremation creates significant air pollution. Consider alkaline hydrolysis or even human composting which can turn a body into top soil in 30 days. https://recompose.life/our-model/

I don't think the pollution is insurmountable. Carbon scrubbers maybe?

Having remains to inter and visit is valuable, to me anyway.
