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.

Pupils Practise Inclusion
When people come together, no matter under what concomitant circumstances – ultimately, it is about how these people meet and how openly they interact with one another.
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.
