The Vulnerable Skin of the Earth

How do sensitive organisms manage to survive in the earth's dry deserts and icy wastes? Which part do they play in these ecosystems? Scientists want to find these answers. By the use of specially developed microtechnology they prove that biological soil crusts protect desert soils from erosion, they photosynthesize, bind carbon dioxide, and prevent desertification. In the earth's arid regions, 50 million km² of soils and rock are covered by biological soil crusts.
