So, how do you propose that we dispose of unclaimed human remains? A big mass grave? Cremation? This is essentially the same thing, the tissues are dissolved and any virus, or disease is destroyed as well - so the remains are sterile - the same as cremation.
Bones are left, unlike cremation - but this uses less energy and is more cost efficient. With millions in cities, and many unclaimed dead - this is becoming a larger and larger problem, it’s not going away.
Me? Don’t really care. What is me will be with God, and when I am resurrected, my body will be remade. Those who died before me, lost at sea, burned or otherwise had their remains destroyed; they will not be “out of luck”. Our bodies are merely vessels for our time on earth. What happens to our bodies, doesn’t matter. What we do while we are alive, that is all that matters.

All I know is, treating our dead with respect is a traditional idea that obviously is so yesterday, and it betrays our lack of respect for human life (the abortion industry, for example). I simply find it offensive as hell that when my Mom dies, her remains could be essentially flushed down the toilet and end up in the waste treatment plant. Dumping remains into sewage plants just seems to me like a slippery slope in the total disregard for human life. And the consequences of that affect all of civil society, which is disintegrating day by day.
