This article comprehensively analyzes the environmental problems arising against the backdrop of the acceleration of the globalization process and their impact on demographic processes. In the 21st century, the deepening of economic cooperation, the acceleration of industrialization, the practice of unlimited use of resources, and the expansion of transnational production chains are leading to a sharp increase in environmental pressure. Such factors as atmospheric pollution, global warming, water scarcity, soil degradation, and a decrease in biodiversity are seriously changing not only natural ecosystems but also demographic indicators related to human life. The study highlights the direct and indirect impact of environmental problems on such processes as the birth rate, mortality rate, migration flows, public health, the quality of labor resources, and territorial demographic imbalance. In particular, in regions with a high level of environmental risk, such demographic changes as a decrease in births, an increase in morbidity, an increase in premature deaths, an increase in ecological migration, and a decrease in population potential have been noted. Also, based on scientific sources, it is shown that factors such as water scarcity or drought caused by global climate change have become one of the main determinants of population migration strategy
