For hundreds of millions of years shit was deliciously licked up by plant life to complete the various cycles maintaining life. It must be handled judiciously but it is part of the life cycle.

Um, poo is the recycling process in action. Without poo there would be no environment suitable for human existance. The plant world depends on animal's poo. Most animals, including humans, depend on plant poo (oxygen).

So let's not go removing it from the cycle just yet. . .

We are generally talking about public parks, where people don't want to sit in the stuff. If we can't bag doo, we can't have parks.

I am not a botanist, but I have seen dog doo kill certain types of grass.

While doo is natural in the forest, etc, domestic dog food is made from some unnatural things, like hormone assisted beef, pork, chicken, etc. I don't know whether natural plants like it.

Instead of plastic bags, how about wax coated paper bags ? The wax would be of a naturally decomposing type. Either that, or bags made from one of the new plastics made from corn silk, etc, that degrade.

hyenuf. um...????....what the? do you poo on the ground in parks? how do we currently take care of poo? we put it through solid filtration and then send it out into the ocean partially treated.

how does human poo become part of "the cycle"

Stevo,

Take a trip to your local waste water treatment plant and you will have a pretty good understanding how the process works. You didn't think they just let it pile up, did you?

I don't know about where you live but around here the water leaving the plant is considered cleaner than the water already in the river. The Department of Natural Resources monitors the effluent to ensure it's not polluting the river.

When waste water enters the plant it is screened to remove the plastics and other nondigestable items. Then it goes into a digester where microbes break down the poo. By the time the microbes are done doing their thing it is mostly water, gas, some oils, and a relatively small amount of solids. The solids are injected into the soil on farm fields and the recycling is begun again.
