Southern Africa's Namib Desert - at first glance, a barren and lifeless setting. Looking closely at the desert floor, however, we see black and multicolored patches adorning the landscape. Regions in Asia and North America present a comparable picture, and indeed, even in the Arctic and Antarctic, the Earth's frigid deserts, such deposits appear everywhere. How can these sensitive organisms survive in extremely dry and cold climates? What state would our global ecosystem be in without them? This program explores the mysterious role that lichens, mosses, cyanobacteria, and green algae play in the well-being of our planet. Viewers learn about the natural microtechnology of these life-forms and how it protects desert environments from erosion while performing photosynthesis and carbon sequestration on a massive scale.
Excellent examples of observations from several continents are provided that show how data are gathered and interpreted, and illustrate how this information has relevance to human affairs. The photography is stunning and the accompanying narrative is lucidly and logically presented....This is a fine example of how to design, conduct, and report scientific work, initially documented in refereed journals, to the entire society. —Science Books + Films (Editor's Choice)
