Snails and Their Habitats
Biodiversity and Survival Strategies
They are slow, really slow ... they are soft, they are slimy ...and greedy. Most of us look at them with disgust. But snails and their relatives are fascinating, useful animals and true survivors. Snails and slugs live on land, in freshwater and in the sea. They have been crawling across our planet for more than 500 million years. The number of species is a matter of estimation. Biologists assume there are up to 100,000. In Germany, their number is limited with about 180 species. Nevertheless, surprisingly little is known about the mode of life of terrestrial snails although some species are very conspicuous.

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.
Youth Movement
Dancing until your feet hurt: Here, at the meeting on the Hoher Meissner near Kassel, 3,500 participants from Boy Scout associations, youth and Wandervogel groups from all over the German-speaking region have gathered. They want to celebrate, simply get to know each other and commemorate a historic anniversary.
