Biodiversity
Threatened Variety of Species
The exact numbers of plant and animal species on earth are unknown. What we do know, though, is that there is a dramatic decline in the variety of species mainly triggered by man. The “threats to biodiversity” as well as their causes are the topics of this film. It illustrates the reckless exploitation of the resources of the earth on land and in the oceans.
Deforestation, overfishing and pollution of the seas destroy habitats and thus an ever increasing number of animal and plant species. The climate change, equally accelerated by humans, also contributes to a speedup of species extinction.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
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.
