what the shovel is to the laborer, and what the truck is to the truckdriver.” 4 In general, composting is a process managed by humans involving the cultivation of microorganisms that degrade and transform organic materials while in the presence of oxygen. When properly managed, the compost becomes so heavily populated with thermophilic microorganisms that it generates quite a bit of heat. Compost microorganisms can be so efficient at converting organic material into humus that the phenomenon is

so, why does it now appear dead? Could a lifeform on its surface have proliferated so abundantly and so recklessly that it altered the planet’s atmosphere, thereby knocking it off-kilter and destroying it? Is that what’s happening to our own planet? Will it be our legacy in this solar system to leave behind another lonely, dead rock to revolve around the sun? Or will we simply destroy ourselves while the Earth, stronger than her Martian brother, overcomes our influence and survives to flourish

another billion years — without us? The answer, if I may wildly speculate, is neither — we will destroy neither the Earth nor ourselves. Instead, we will learn to live in a symbiotic relationship with our planet. To put it simply, the human species has reached a fork in the road of its evolution. We can continue to follow the way of disease-causing pathogens, or we can chart a new course as dependent and respectful inhabitants on this galactic speck of dust we call Earth. The former requires only

In China, current standards for the agricultural reuse of humanure require an Ascaris mortality of greater than 95%. Ascaris eggs develop at temperatures between 15.50C (59.90° F) and 350C (950 F), but the eggs disintegrate at temperatures above 380C (100.40° F).28 The temperatures generated during

the water, reported as the number of coliforms per 100 ml. Such a test measures all species of the coliform group and is not limited to species originating in warm-blooded animals. Since some coliform species come from the soil, the results of this test are not always indicative of fecal contamination in a stream analysis. However, this test can be used for ground water supplies, as no coliforms should be present in ground water unless it has been contaminated by a warmblooded animal. Fecal
