It’s an interesting topic. If you take a pile of wood and put a match to it, the same amount of “pollution,” is generated if it had been left to decompose. I believe the same is true of the human body.
There are arguments, discussions I’ve seen around “what about people eaten by animals, killed by sharks, blown up etc.” Every human ever born has died on this planet so they’re part of the biosphere that we call Earth i think a handful of ashes have been launched into outer space).
Everything that they were made of is still here and I believe can be made whole through God. I’m putting way to much thought into this, but I just can’t see putting $10k in the ground.
Dittos on the 10K in the ground. Better to spend that money while living. But in death, like life, people like to show off. And funeral homes are only too happy to take your money.
In that respect I think of Christ and his body after the resurrection. His old one had vanished, but was it the same one as his new body? The new one could change form, appearing like a stranger to his disciples, or again as his original one, or as a glorified one. Angels in the Bible could either take the form of normal humans, or their real form, beautiful and full of God’s glory. I don’t think normal matter is capable of that.
