International Day for Biological Diversity What does ore mining have to do with forestry? What impact did the straightening of the Rhine have in the 19th century? How did a whale support the installation of filter systems in factories? To mark the International Day for Biological Diversity, this tour through 800 years of German history sheds light on how human activities have changed nature and biodiversity. Selected objects such as a potato made of plaster, documents about a successful commons on Lake Constance, a motorcycle or a model of a shovel excavator are used to present forms of land use, economic interests and technical developments and to classify their effects on habitats. The view of societies on nature is addressed as well as the protective measures and nature ideologies in the respective political government systems.Translated with DeepL
