I wholeheatedly agree with you Dave.

Question, have you ever heard of the human nutrient cycle?

There is far more than just mere nitrogen in human poop. There is potassium, phosporous, zinc, iron, sulfur, and at least 70+ other nutrients.

Most diseases are the result of a nutritional deficiency. By recycling poop into fertilizer, we can actually extend the average life expectancy in the U.S.

Using human manure is probably better than using the cow manure they normally use. Cow manure usually carries E. coli and other microbes that are pathenogenic. Human manure also contains coliforms and such, but they aren't as dangerous if they get into the food supply. And healthy1 has a point...putting nutrients back into the soil can't be a bad thing, right?

Yes runningirl. The most safest way to use any manure, is to hot compost it first.

Hot composting involves getting the manure to a temperature between 131F and 170F for a specified amount of time. One of the fastest ways to get this accomplished is to mix the manure with aorher organic matter (especially grass clippings and hay). The heat produced by the decomposition kills the pathogens and any parasites.

Ultimately, everything biodegradable is recycled, whether intentionally or not. The question is what percentage of what ends up where at various times during the recycling process. Runoff from land, whatever course it takes, ends up in the oceans, and that is eventually evaporated and returned in the form of rain. So however our sewage is discharged, it does eventually return to the food chain, perhaps not in as concentrated a percentage as it would be if it were purposely added at some juncture.

Humans and animals were pooping all over the planet before anyone ever thought of sewage treatment or fertilizer. All that poop biodegraded and, again, was returned to the food supply eventually in modified form.
