>>NAIROBI, Kenya, November 29, 2002 (ENS) - There is a wealth of new
>>species under our feet awaiting discovery, especially in the still
>>unknown portions of the tropics, which represents "a huge new
>>genetic resource," the top United Nations environmental agency said
>>today. Amoebas, protozoa, netatodes, mites, termits, ants,
>>earthworms. Life forms that inhabit the soil are the least known of
>>all life forms on Earth, and scientists are discovering that they
>>can profoundly affect planetary patterns.
>>
>>Calling it "the largest source of untapped life left on Earth," the
>>UN Environment Programme (UNEP) has announced a new $26 million
>>project to understand and utilize the life forms underground. It is
>>one of the more "unusual, curious but absolutely vital projects
>>UNEP has undertaken," said the agency's executive director Klaus
>>Toepfer as he announced the project today.
>>
>>In the hope that this "genetic treasure trove" will yield new
>>drugs, antibiotics, and industrial products, the project will
>>initially target "below ground biodiversity" in seven tropical
>>countries - Brazil, Mexico, Cote d'Ivoire, Uganda, Kenya, Indonesia
>>and India. These countries were chosen for study are those thought
>>to have the richest below ground biodiversity.
>>
>>Backed with $9 million funding from the World Bank Group's Global
>>Environment Facility (GEF) and support from other donors such as
>>the Rockefeller Foundation, the Conservation and Sustainable
>>Management of Below-Ground Biodiversity project will catalog and
>>classify "the life forms below ground" said Ahmed Djoghlaf, head of
>>the UNEP/GEF Division, based at UNEP headquarters in Nairobi.
>>
>>One gram of tropical forest soil may contain up to 40,000
>>individual bacterial species, the agency said today, many of which
>>have never been described.
>>
>>These miniscule life forms can be as tiny as one-tenth of a
>>millimetre (100 micron). The smallest amoebas are even less than 10
>>micron in size.
>>
>>"There is an urgent need to assess, classify and record the life
>>forms below ground," Djoghlaf said.
>>
>>Just as increasing intensification of agriculture and clearing of
>>forests for farmland have taken their toll on wild animals and
>>plants, they place the microscopic world of underground bacteria
>>and fungi at risk of extinction and decline in the abundance and
>>numbers of species.
>>
>>UNEP Executive Director Klaus Toepfer said, "The life forms living
>>just below our feet are the most understudied organisms on the
>>planet. When people think of where new species might be found, they
>>tend to think of the rainforests, mangrove swamps or place like
>>mountain peaks, not millimetres below their toes."
>>
>>Toepfer said researchers are now realizing that the world's soils,
>>especially topical soils, are teeming with life. They "harbor more
>>undescribed species than dwell on the Earth's surface," he said.
>>
>>Expressing delight at UNEP's involvement in "this pioneering work."
>>Toepfer said, "Harvesting the secrets of this understudied realm
>>promises huge benefits and improved knowledge towards the goal of
>>delivering sustainable development, towards eradicating poverty."
>>
>>Bacteria and fungi in the soil can clean drinking water sources.
>>They help eliminate pollutants and germs from groundwater as it
>>percolates through the soil to reservoirs, boreholes and other
>>freshwaters sources.
>>
>>Organisms living in the soil also "play a key role in the release
>>of carbon dioxide, methane and other greenhouse gases from the land
>>into the atmosphere," scientists associated with the project said
>>as part of the UNEP statement today.
>>
>>Understanding and unraveling the role of these microscopic
>>creatures in the carbon cycle may help the land absorb more
>>greenhouse gases to help cool the planet.
>>
>>Soil-dwelling beneficial life forms may also play a role in
>>reducing crop, livestock and human diseases, UNEP said today, as
>>they attack and neutralize plant, animal and human pests and
>>pathogens.
>>
>>Earthworms, termites and other soil burrowing organisms influence
>>the amount of rainwater soils can absorb. Soils depleted in such
>>organisms are more prone to drought and run-off, which in turn
>>increases the risk of flooding and erosion with consequences for
>>river water and coral reefs.
>>
>>"We may be losing many important and useful species from the
>>world's soils without even knowing it," warned Djoghlaf.
>>
>>The project is coordinated by Mike Swift, director of the Nairobi
>>based Tropical Soil Biology and Fertility Institute of the
>>International Center for Tropical Agriculture (CIAT), one of the
>>research centers in the CGIAR agricultural network.
>>
>>The Consultative Group on International Agricultural Research
>>(CGIAR), an association of public and private members supporting a
>>system of 16 Future Harvest Centers, works in more than 100
>>countries, mobilizing the "cutting-edge science" that CGIAR says
>>aims to reduce hunger and poverty, improve human nutrition and
>>health, and protect the environment.
>>
>>Increasingly, bioengineering and genetic modification of crops
>>underpins CGIAR's approach to those issues. Still, CIAT has other
>>offerings, among them a new climate database tool based on 20 years
>>of weather data. The newly published CD-ROM version 1 of MarkSimTM
>>generates Simulated Weather Data for Crop Modeling and Risk
>>Assessment.

>>Worms and Fellow Soil Dwellers"

>>Over 4,000 bacteria and related organisms have been described by
>>science, an unknown number of which are soil dwelling. It is
>>estimated that in one gram of forest soil there are up to 40,000
>>individual bacterial species many of which have never been
>>described.
>>
>>It is thought that only five percent of the world's living fungi
>>have been described. Of the 72,000 described species, up to 35,000
>>could be classed as soil living.
>>
>>Protozoa include amoebas and flagellates. Some 1,900 soil-living
>>protozoa have been described, which may be only 10 percent of the
>>species alive.
>>
>>Some 15,000 individual nematode species have been described. It is
>>estimated that there may be more than be as many as 100,000 species.
>>
>>The 45,000 described species of spider-like invertebrates known as
>>mites are thought to represent just five percent of the total.
>>
>>There are numerous groups of soil-dwelling insects, including
>>termites. More than 2,000 termite species have been described.
>>
>>Nearly 9,000 ant species have been described.
>>
>>Over 3,600 earthworms have been described, and scientists say
>>double this number may exist in the wild.
>>
>>Most protozoa eat bacteria, says Elaine Ingham of Oregon State
>>University, but one group of amoebae eat fungi, the vampyrellids
>>that suck the life out of their prey.
>>
>>"The perfectly round holes drilled through the fungal cell wall,
>>much like the purported puncture marks on the neck of a vampire's
>>victim, are evidence of the presence of vampyrellid amoebae," says
>>Ingham. "The amoebae attach to the surface of fungal hyphae and
>>generate enzymes that eat through the fungal cell wall. The amoeba
>>then sucks dry or engulfs the cytoplasm inside the fungal cell
>>before moving on to its next victim."

>>biodiversity are online at the website of the U.S. Department of
>>Agriculture Natural Resources Conservation Service's Soil Quality
>>Institute, UNEP recommends. Find it here.

>>An old Cherokee is teaching his grandson about life. "A fight is going on
>>inside me," he said to the boy. "It is a terrible fight and it is between
>>two wolves. One is evil - he is anger, envy, sorrow, regret, greed,
>>arrogance, self-pity, guilt, resentment, inferiority, lies, false pride,
>>superiority, and ego." He continued, "The other is good - he is joy, peace,
>>love, hope, serenity, humility, kindness, benevolence, empathy, generosity,
>>truth, compassion, and faith. The same fight is going on inside you - and
>>inside every other person, too." The grandson thought about it for a minute
>>and then asked his grandfather, "Which wolf will win?" The old Cherokee
>>simply replies, "The one you feed."
