Was ist Was - Forces of nature/air and water

The audio play 'Natural Disasters' tells about volcanoes, earthquakes, tsunamis, and hurricanes, depicting the destruction they can cause. People do not always manage to get to safety in time from the unleashed forces of nature. Without air and water, our planet would be a desert. In daily life, we often pay little attention to these two important elements. The nature of these elements and how much all living beings depend on them can be learned from 'Air and Water'.
