Environment and Ecosystem

“To be brought back down to earth” is an expression we use when someone needs to come back to reality. Just like the air to breathe, the soil is taken for granted and simply there – we do not need to think about it. However, it is an extremely complex, sensitive structure and not only the crucial production factor for farmers but their basis of their existence. Ultimately, the soil is the vital basis of life for plants and, directly or indirectly, for animals as well as us humans. Starting from the relevance of the soil, the film clarifies the diverse, mutual relations with other elements of the landscape. In this cinematic exploration, the manifold, soil-forming factors and processes such as, for instance, decomposition and humus formation are explained just like the geographical basic terms “soil profile”, “horizons” and “soil type”. Over the past 150 years approximately, a profound change has taken place in agricultural production, which was essential to provide a stable, high-quality sustenance of the growing population in the industrial states. The DVD also shows that heedless human interference into the soil ecosystem has brought about irreparable consequences.
