In the near future, the "superorganism mankind" will be confronted with an avalanche of drastic changes, so-called "game changers". All living beings and the communities they form are complex interaction networks. They are made up of a multitude of components that influence each other and are therefore difficult to understand and predict. Only with a comprehensive understanding of the complex systems of our living environment can society be prepared for these changes. The understanding of such systems should provide science, business and politics with the necessary basis for decisions in terms of sustainability.
