Difficulties in the holistic assessment of human impacts on the environment lie in defining the relevant criteria and delineating the affected environment. This book provides assistance in this regard. The author has also systematically organized and explained the previously used 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 the assessment are aligned with the legal requirements that are crucial for practice. This has allowed for the identification of gaps and deficiencies in the existing legal regulations.
