Difficulties in the holistic assessment of human impacts on the environment include defining relevant criteria and delineating the affected environment. This book provides assistance in this regard. The author has also systematized and clarified the previously inconsistent terminology. This establishes a solid foundation for both practical application and further scientific discussion. The author's considerations are designed to be cross-media and interdisciplinary. Scientific requirements for assessment have been aligned with the legal requirements that are crucial for practice. This has allowed for the identification of gaps and deficiencies in existing legal regulations.
