Our Forest as a Climate Saver!?

In the context of climate change processes, natural CO2 storages play an important role as parts of
the carbon cycle. This unit focuses on the forest as a carbon sink and asks the question of relations
between the binding of CO2 in Germany’s forests and the emission of greenhouse gases within Germany. With the help of satellite images, the pupils get an overview of the distribution of forest areas in Germany. These insights are linked to background information to solve the central problem.
