The article presents the concept of threats from the human environment, analysing their origin, structure, and division into natural and anthropogenic threats. The research niche of this article is a conceptual refinement of environmental hazard classification by introducing the category of “threats from the human environment”. The purpose of the article is to organize information about dangers whose sources are found in the environ-ment (natural and artificial - anthropogenic), their classification, and a brief description. During the considera-tions, the following research question was posed: "Does the classification of natural hazards adopted in litera-ture reflect the ubiquitous impact of human activity on the environment today?" As a result of this question, a hypothesis was put forward that the division present in the literature is not adequate to the realities of the modern world. The study used the method of existing data analysis, covering theoretical classifications and literature in the field of safety and ecology sciences. A comparative analysis technique was employed to com-pare different classification models, enabling the identification of common features and elements that distin-guish individual approaches. The study also employed content analysis to construct a theoretical framework of threats arising from both natural processes and human activities. The results indicate the dominant influence of civilizational factors on contemporary environmental threats and the interpenetration of both risk catego-ries. The conclusions emphasize the need for a systematic approach to ecological safety and the introduction of a category of threats from the human environment as a tool for organizing risk analysis.
