What?!?? I just tap my finger on the glowy thinking rock and demons/faye/angels take my messages to other people’s thinking rocks and bring me their responses. I don’t believe in all that ‘electricity’ witchcraft!
Seriously, yes burial uses a fair bit of space, which is part of the reason cremation is increasing in popularity in many places. Even with burials though, many graveyards reuse plots after some number of years, once the previous body has decomposed to save space. For those wanting a more ecologically friendly method than cremation, there’s the option of resomation too.
