Biodiversity
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.

Fish Farming
Lakes, rivers and streams are the natural habitats of our freshwater fish. Some of them, such as carp, trout and char, are eaten as food fish. But where do the fish come from and why have our lakes and rivers not been fished dry yet? Since the Stone Age people have been catching fish for subsistence. Fish is an important source of protein. With a wide variety of methods, such as fishing rods or nets, we hunt them successfully.

Invertebrates
The term “invertebrates” was coined by the French zoologist and botanist Jean-Baptiste de Lamarck in the early 19th century. He was the first to address the classification of the then so-called “lower animals” and divided them into different categories and classes.

Mammals I
When we talk about animals in everyday conversation, we mostly talk about mammals. Mammals live in water, on land and in the air. Countless species of the most diverse sizes and appearances populate our earth. A clear classification is not always possible because of their adaptation to their different habitats.

The Honey Bee
Untiringly, the honey bees fly from flower to flower, constantly in search of pollen and sweet nectar. These busy workers live together in a complex social system an insight into which is provided by this film. In vivid pictures, it describes the life of the honey bee in the bee colony and deals with the inhabi- tants of the beehive and their strict division of labour. It shows the worker bees foraging for food and communicating with each other in their characteristic way. The second part of the film illustrates how a new bee colony is formed and describes the course of a bee‘s year from the new queen to the mating flight and the brood cells and finally to the expulsion of the drones in the „slaughter of the drones“. The DVD and the didactically arranged worksheets are per- fectly suited for the classroom both as an introduction to the topic and as a tool for the pupils when working individually or preparing projects.

Bats
Bats are the only mammals that can fly actively. In mythology they represent the dark element and were the inspiration behind the invention of vampire stories. On account of their nocturnal way of life and their dark appearance, they are considered scary by many people. But the nocturnal hunters are by no means keen on human blood. They mainly hunt insects, thus assuming an important role as natural pest controllers.

Hunters and Hunted
The African night is not for sleeping. A lot is going on there. The hunters are lying in ambush and the preys are on alert. Predators are mammals. Scientifically they are called carnivores. But other predatory vertebrates such as cats, jackals, hyenas and crocodiles are colloquially termed »predators«. They feed on meat but are not very selective in doing so. As they are not specialised in one type of animal but eat all vertebrates as well as carrion, they are called opportunistic feeders, which means they target the food that is easiest for them to catch, in the shortest time and with minimum energy input.
