Desert
Types, Vegetation, Fauna
Deserts and semi-deserts cover roughly a third of the entire landmass of the Earth. A huge area of our planet is thus defined as an arid region. But what exactly are arid regions and are they similar everywhere? In general, landscapes where only highly specialised plants or no plants at all can grow due to their extreme dryness are referred to as arid regions. Therefore, cold deserts also fall into this category. Although they have water, it is frozen due to the cold and thus not available for plants. In addition, the lack of vegetation is caused by the lack of warmth. The marginal zones of the polar regions Arctic and Antarctica i.a. count among the cold deserts, but also the alpine cold deserts of high mountains. The picture is entirely different with arid deserts. In arid deserts, little precipitation and a high rate of evaporation are mainly responsible for the lack of an extensive vegetation cover. Most arid deserts stretch out around the globe in two broad dry belts north and south of the equator.

Internet Addiction
The film consists of two parts. The first part is the 15-minute short film “In the Net”. It describes the problem of excessive Internet use in a humorous way, in particular the risk of losing touch with reality when chatting. The second part illustrates with three real persons how Internet addiction can develop and the problems encountered by those who are afflicted. The authentic statements are commented by an experienced therapist. For many pupils, the issues addressed here are related to their everyday lives. What is a “sensible” use of the Internet, where does pathological addiction start? In contrast to addiction to alcohol, nicotine or drugs, the public seems to be largely ignorant of the problem of this addiction, which is not related to any substance abuse. The film provides material for discussion in the classroom (crossdisciplinary) and can be used as a basis for the formulation of prevention strategies.

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.
