That picture is hilarious.
Also, Jack Jack, bodies are the property of next-of-kin. If you decided that you wanted to bury a thousand dollars in the ground, I could say "Giving it to charity is a better use of that money" all I like, but I can't force you to give it to charity as opposed to burying it. This is the same situation-yes, donating organs or even using it as fertilizer may be a better use of it for the community, but if the individuals who own the bodies (family members) want to bury it, no one has a right to stop them.
