This work written in an understandable way for the interested layperson introduces into the
unknown world of the CO 2 gas volcanoes the so-called mofettes. A little explored world that
lets animals die in the middle of Europe changes the flora influences soils and the
atmosphere and can provide clues for upcoming volcanic eruptions. With the help of the
botanical bioindication such degassing points can also be found in the field and even used
economically e.g. in mineral water and fire extinguishers for the preservation of food and
for the healing of heart and skin diseases. In this biological-geological mofette guide Prof.
Hardy Pfanz explains where such phenomena can be found in Germany but also worldwide and what
they tell us. He also reveals - with a wink - one or the other extraordinary and legendary
thing about mofettes.
