Two Problems:

That means two problems as opposed to one. The first problem is that of cannibalism.

Inbreeding Problem

It might be similar to the problem of inbreeding, that is when a son get his own mother pregnant. That has something to do with the DNA and how babies are made via mixing from the genes of the mother and the father.

Birth Defects

If the father is from the mother, that tends to result in birth defects. So, many people have buried the dead. Usually, we find them sleeping at cemeteries.

Why do people avoid eating people?

There may be reasons why we keep bodies in coffins as opposed to in a compost pile. Perhaps, the ancient world knew why. Perhaps, there are reasons behind it. Perhaps, some people are unaware of what those reasons might be.

Chemical Residue

A second problem is in what chemicals may have been used to break down the bodies.

Back Into The Soil

Because those chemicals, those things, can go back into the soil and into the plants, the foods, the animals, the people.

The Cellular Level

It can be tough to know as some of this can happen on a cellular level. That includes the dead body parts.

Cannibalists Get Sick

People who eat dead bodies get diseases.

Zombies

Some of it goes into the brain of the consumers.

Pork, Shrimp, Lobster, Etc

When people eat shrimp, lobster, pork, etc, they get stuff that the body hates. Bad stuff happens.

Recycling Bodies

Now, is it possible to recycle a body eventually and well enough in order to later reintroduce it back into the soil? I don't really know. I would hope so. Maybe wait a thousand years. 30 days might be too quick.

Atomic Level

But regardless of that, perhaps the dead body would need to be broken down at the atomic level as opposed to just the cellular level because there can be bad things from the cells that can then be consumed later on by people. Now, you might be able to blow dead bodies up with an atomic bomb.

Bombs

Maybe that would break the bodies apart into tiny pieces at the atomic level. Well, maybe some of it.

Radioactive Spider Zombies

But then that introduces a third problem, and that would be whatever the bomb leaves. As in radioactive garbage or whatever.

Kick That Can Down The Road

I would procrastinate from eating dead bodies for like another thousand years. Let the future people make those kinds of choices. I don't think people have to eat dead bodies right now.

AOC

But some people think the world is going to end in like Agenda 2030, that is in less than twelve years. Oh, AOC, we need to eat babies? AOC couldn't say no.

Seattle

They are doing this in Seattle. I live near Seattle. So, I am concerned with this.
