Becase human waste is filled with all the nutrients ats added in our food...t would be unhealthy....its oly herbivore animalslike cows thats waste gets used as ferilise because i isn't fille with chemicals.

Answer 8

You can but it can spread disease I wouldnt use it on crops but I heard they actually do this in some parts of korea. google or Yahoo 'human f***s fertilizer'

Answer 9

Hummm...

>It's hard to "collect" ?

>Neighbors usually frown upon seeing it "deposited"

>Toilet Paper looks messy in the Garden?

But I suppose if human waste, where used "Babies" could have a new use

instead of diapers you could just use a baggie

"Johnny Jumpers" could be used without diapers and be renamed "Johnny Dumpers" ( just hang child in jumper over the Garden)

I dunnnno

maybe just cause Hummans "p**p" stinks due to the fact that most eat meat.

Peace

Answer 10

It could, but you might get sick if you eat some of the bacteria. Plus human waste would probably be much more toxic than that of other animals due to the artificially tampered with foods we eat, and artificial man-made drugs we consume, etc.

Answer 11

It is used daily on some farms in PA. Actually, there is a case before the PA Supreme court right now where a farmer is being ordered to stop using human waste on his fields by the township.

Answer 12

It is used.

I never see it but my grandfather who is a farmer told me that at the past they have used it and it is proven to be much better than animals' or the Artificial.

He said that vegetables and fruits was bigger than today's.

The problem arises with the bacteria that live in human waste. It takes a lot of heat to kill these bacteria, and people are afraid that contamination is an issue. If, however, the waste is treated properly then there shouldn't be an issue.

Hope this helps!

Answer 14

It can, our waste isnt any different than animal waste.

Ł๑\/əЯ is wrong though.  Animals (Livestock, Domestic) get shots/vaccines like us, and most get fed processed foods & hormones.

Answer 15

It can, but it is usually treated in a digester first, then sprayed onto farmland. There is a max annual dosage per acre, but that has more to do with heavy metal contamination than any bacteria problem as the digester process kills them. It makes a good general fertilizer/conditioner.

Answer 16

It has been used for years. Asian cultures have done it for centuries.  Some people feel it is not safe, including environmentalists. Apparently it is concern about human waste fertilizer blowing in the air.

Answer 17

This is cuz we eat too much junk food. Think about it..animals whose waste are used as fertilisers are Vegetarians right? Rabbits are herbivores and they eat their own waste again and again to make sure all nutrients are extracted. Herbivores have nutrients in their waste and thus can be used to fertilise fellow plants. But as for humans, we eat meat and alot of unhealthy stuff... they contain fat and alot of other unhealthy stuff that has no positive nutrients to fertilise the plants.

Answer 18

It can, however the effect is so minimal that it's close to being pointless. The whole point of fertilizers is to provide plant nutrients which are deficient in soils. But with the variety of foods we eat, plus the diseases/parasites  we carry... the risks just outweigh the rest.

We use it for landfills though ;)
