Are there any stocks for green burial/tree pod burial companies?

Aside from the fact it’s always been my plan to be used to grow a tree after I die, I think with the current environmental problems green burials are going to pick up, maybe not in the short term but as it gains more and more traction I expect it to be a big thing in the future, and I’d like to get in earlier rather than later(the stocks that is not the pod)
