And then there is the highly questionable use of raw sewer sludge as a fertilizer.
Yes, you heard me
right. In some countries, raw, uncomposted and untreated human waste is applied directly to crops and
soil,
a practice known as "night soil" since it's typically applied at night.
The risk of disease is obvious
and high and this practice should never be confused with "humanure", a long,
highly involved process
of decomposing human waste into a safe resource.
