The Green Paradox
Why the Earth Gets Warmer
Carbon dioxide is a nontoxic gas. It is formed in our bodies and in nature in the combustion of carbons. These are contained in all organic materials. Carbon dioxide - or simply CO2 - is a so-called greenhouse gas. It causes the greenhouse effect thus determining the climate on our earth. This is what enables life on earth as we know it. But when the greenhouse gases are increased by man, the blessing may soon turn into a curse. This intensifies the greenhouse effect and heats the earth up. The resulting climatic change is the big problem of our century.

Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
