I read a position paper on this.
With the Chinese laws against having more than one child for decades, coupled with infertility rates and a rising age of the global population... famine, war, starvation (at el), the next 30 years will witness a significant die off.
What needs to be done in the present is to figure out what and how all the cadavers will be efficiently disposed of.
Traditional burial rights and practices are probably not going to be feasible. The Chemicals alone might be harmful but will breakdown over time.
Cremation takes energy that nobody willing would care to expend. Perhaps composting bodies and returning the compost back to areas where the soil has been degraded through synthetic petrochemical agricultural practices is gaining traction.
In 50 years, with large swathes of the global population gone through natural attrition, it might be pretty nice around here.
Globalists desire a die-off but well before 30 yrs have passed. Thus, some among that ilk are already conditioning people to accept cannibalism as a source of protein. And really, since certain Westerners have no problem with cannibalization of the just born for body parts, then why not consume adult human meat.
