In what way? How does the body traverse through dirt, and the dirt doesn’t?
I am for it as long as measures are taken to keep critters away. You wouldn’t want some coyote digging up Uncle Joe and gnawing on his leg.
Bodies are mostly water, and after death with no preservatives, they rot like last month’s cabbage in the back of the refrigerator. If not contained securely, body fluids seep into the soil. Rain drives decomposing flesh deeper and deeper.
