Cremation has become the preferred way to honor the deceased, as burial plots are becoming harder to find, and an overly expensive burden, competing for scarce usable land.  Locking away more lands from development is compounding the problem.  As our population continues to grow, more land is needed.  More mineral development requires land.  Roads, railroads, pipelines, factories, power-lines, and businesses all need land.
Governments should keep some reserves in land, but not treat those lands as sacred, refusing to release them as needed, just to have a feel-good.
