  • Probably because we create so little? And cows, and larger animals create a lot more.
  • It is. Some local governments process human sewerage sludge and sell it commercially as fertilizer.
  • First off, some people are concerned with disease and the use of human fertilizer on food crops for people is still considered a no-no. But there are many places that process their sewage and them spray it to water and fertilize areas where there are no food crops or human traffic like along freeways or for erosion control.
  • After it is treated, I would say that it should be used to combat land erosions and desertification in the areas at risk and then they can plant grasses in it or something. There is just too much harmful bacteria in sewage and that would poison all the farmland.
  • Inorganic fertilizers are sterile, and possess no risk of contamination by toxins, heavy metals, bacteria, or other items. Amongst the organic fertilizer types, there are fish emulsions, dried seaweed and so on, which also possess no concern with contamination from toxic items. Human waste, however, contains that which has been rejected by the human system. It contains bad bacteria, poisons, drugs and chemicals which individuals have ingested, and so on. Human waste is far riskier to use for fertilization purposes, and would necessarily need to be treated to remove contaminants which would be harmful to man or animals and thoroughly tested prior to packaging. There are actually organic fertilizers currently on the market such as “Organo”, “EKO Organic Compost”, and "Milorganite" which are produced from "processed" sewage sludge. These items are not allowed for organic farming however in the USA. http://www.newfarm.org/columns/org_news/jan05/org_fertilizer.shtml "Biosolids shouldn't be used until we improve waste treatment methods," says John Bennett of the Sierra Club. "There is so much international travel happening that parasites enter ecosystems through travellers. This affects the digestive tract, turning up in our waste. "The current sewage system provides for temperate, seasonal climates," he continues. "Studies have been done in the United States which show treatment temperatures insufficient to kill parasites. We aren't checking for this. We look for E.coli, but must expand the testing regimen to prove that all bacteria is dead. Until that is done, it's a risky game." http://www.perc.ca/PEN/2001-02/s-mills2.html One example of the risk involved, and why fertilizer made from human waste products are not allowed for food production in the USA can be found in this article - http://www.commondreams.org/archive/2008/03/07/7533/
  • In some countries and societies it is. Not in what we call a civilized country, however. No matter how you treated it and how safe it was, it would not be acceptable for growing food for human consumption. So, what happens to it?? http://www.perc.ca/PEN/2001-02/s-mills2.html http://www.greatlakesdirectory.org/mn/101203_great_lakes.htm http://www.worldwatch.org/node/5394 Google references: http://www.google.com/search?hl=en&q=human+waste+as+a+fertilizer&btnG=Google+Search
  • Not unless it's sterilized. Much of the developing world uses it as such, but subsequently have higher rates of food-borne illnesses. Which is why travelers are advised to never eat any produce in third world countries that has not be washed, boiled, peeled, or a combination of the three.
  • Nope. And to top it off because of all the meat we eat it just isnt good fertilizer anyway. cow shit is good because they eat only plant matter which when broken down helps grow new plants
