   More evidence of ancient ‘terra-forming’ of the earth to make it habitable for higher life-forms:

   Cryptobiotic Soils: Holding the Place in Place
   Excerpt: Cryptobiotic soil crusts, consisting of soil cyanobacteria, lichens and mosses, play an important ecological roles,,, Cryptobiotic crusts increase the stability of otherwise easily eroded soils, increase water infiltration in regions that receive little precipitation, and increase fertility in soils often limited in essential nutrients such as nitrogen and carbon (Harper and Marble, 1988; Johansen, 1993; Metting, 1991; Belnap and Gardner, 1993; Belnap, 1994; Williams et al., 1995).

   Bacterial ‘Ropes’ Tie Down Shifting Southwest
   Excerpt: In the desert, the initial stabilization of topsoil by rope-builders promotes colonization by a multitude of other microbes. From their interwoven relationships arise complex communities known as “biological soil crusts,” important ecological components in the fertility and sustainability of arid ecosystems.

   CRYPTOBIOTIC SOIL –
   Excerpt: When moistened, cyanobacteria become active, moving through the soil and leaving a trail of sticky material behind. The sheath material sticks to surfaces such as rock or soil particles, forming an intricate web of fibers throughout the soil. In this way, loose soil particles are joined together, and an otherwise unstable surface becomes very resistant to both wind and water erosion.

   This is so true. They’re the ultimately recyclers and we need their trillions X Trillions and more of their numbers or our goose would be cooked. The incredible thing is the amount of information that is packed their tiny bodies that allow them to engineer themselves to take on whatever task come what may. Given human idiocy and irrresponsible knack for creating tons of filth, we need all the help they can provide. Nylonase comes to mind.

   Not sure this paper says what you think it does.

   Could News elaborate on the issue here?
