In my country Pakistan and neighboring country India cow’s dung is mixed with hay and dried as cakes to be used as fuel.The cattle shed wash is used to generate biogass which is methane, again used to turn turbines and light stoves.Eating of feces in hogs and pigs is a common observation.That is why its flesh is riddled with parasites and not considered fit for human consumption in many cultures.

Great post Zach,
According to Nick’s comment, Manure from animals and typically humans do benefit farmers and gardeners for growing healthy plants using the nutrition, but it also is very fatal to humans prior to sanitation. According to an article in the NY times, dating back to 2008, one of the biggest issues amongst areas around the world affected by poverty is the simple lack of a safe, sanitary place to defecate. unfortunately as the author wrote, approximately 2.6 billion people face this problem everyday, defecating about 200 tons of untreated faces daily. every year, more than 1.8 million people, mainly children, die prematurely from exposure to water tainted with human feces. the reason Human Feces is very fatal is because they carry viruses called Pathogens. In fact, a child’s feces carries more pathogens than an adults feces. In my link, a video by UNICEF (United Nations International Children’s Emergency Fund) explains that every dollar invested in sanitation results in a tenfold return in increased productivity and tourism. it may well cost about cost about $10 billion for the number of people without basic sanitation, but it will save $100 billion for the costs of education and health benefits.
here is my link to the article:

Nice post Zach, very intriguing! I see no one answered your question above, “Can feces benefit humans in any sort of way?”, which is the question i found the most important. At first I was not sure how feces of all things can benefit a human, but after a bit of research i was amazed with what we can do with it. We use manure, which is a fertilizer for our soil. This helps out a farmer, or gardener a lot because without this, there is a lower chance of their crops to grow successfully, and when you add manure it is more likely for a healthy plant. I am very glad you posted this post, because it was very informative. This website below gives more information about the necessities of manure.

Great post, Zack!
Adding on to what Leyla said, many animals eat the stool for nutritional purposes, but not all animals do it for nutrition. Koalas, for example. They eat the stool of the parents, not for nutrients in the stool, but for certain poisens that are in the stool, by injesting the toxins in the stool, the cub will have built an immunity to it by adulthood, and will be able to eat the normal koalas diet, eucalyptus leaves.

Hey again. I just wanted to add a way that feces benifits and has been benifiting humans for a very long time. Plants. We eat vegetables fruits and many other plants, and they give us nutrients. In the past fertil soil was sometimes sucked dry of its nutrients because of overuse and people had to move to another location to start all over again. But man found a solution, feces (AKA manure). They used cow and horse manure to fertilize their plants and keep the soil healthy. Manure gives plants an immediate supply of nutrients,lowered pH, improved soil structure and much more. if you want to find out more information on this topic please click on the link below

Great post Zach! After doing some research I found that there are farmers that live in places like China, India, and Vietnam where prices of fertilizer are rising. As a replacement, they use their own raw sewage on the crops. Although there are health risks and it seems highly unethical, it can actually serve the farmers well. For example, they prefer wastewater because it is high in nutrients such as nitrogen, phosphorus, and potassium. It also costs much less than chemical fertilizers.

Well actually, there’s a simple and very common form of this happening in your own backyard! Well, sort of; manure is a naturally occurring fertilizer that can come from cows, horses, chickens, sheep and rabbits. “Manure” is just another name for poop. While humans buy these manures and spread it artificially on their lawns to fertilize grass and other plants, this occurs naturally on valleys and places where cattle or other animals previously listed are kept. They eat the grass, poop, and their poop fertilizes the very same ground, allowing grass to grow again. This fertilization is made possible by worms and other animals and insects.

This link shows how my last example of natural fertilization is true, however there is a pop-up, however you do not have to subscribe, you can simply scroll to read above the popup, as you cannot close it either, as far as I know, the article isn’t solely about this either, but it does have statistics about the topic at hand.

This link is specifically about how worms help the fertilization process along:

Great post Zach. To answer the question, what benefit does the excretory process have on human beings. Well, The human being is a mammal so we have organs systems dedicated to the excretory process. The benefit of excretion, is waste and extra indigestable substances or poisons are removed from the body. If they built up in our bodies, problems would ensue. In fact if the poisons weren’t removed we could die.
I am over generalizing of course because “pooping” is the intestinal excretion process. There are more than one in the human body. Breathing and releasing carbon dioxide is one, and perspiring is another.

Nice post, Zack recently a Seattle aquarium started doing tests on wild sea otter feces to settle why the sudden severe drop in population. their feces have determined some of the reasons why and one of those is that the otters are under a lot of stress and this is preventing the otters from meeting their biological goal. The otters are also pooping out reproductive hormones before they reproduce this also is effecting the offspring so that some of the offspring doesn’t survive. Their feces may help in restoring the population but the scientist have not finished their experiments yet.

Very interesting post, Zach! I never knew that poop could be so beneficial to our environment. I did a little more research on poop and how it could be beneficial. Scientists have discovered that by measuring the size of chinchilla poop, the amount of rainfall in previous years can be determined. Chinchillas poop in small scrap piles, which are full of plants and feces that chinchillas glue together with their urine. By pooping, chinchillas living in Chile’s Atacama Desert are helping scientists to determine the rainfall pattern within the region for the past 14,000 years. It is crucial to know previous rainfall patterns in order to predict Chile’s future water supply, and this is all able to occur as the result of tests done chinchilla poop.
