Repercussions of ecological agents for the human organism. The present work represents a study of the peculiarities of sustainable development as part of the survival strategy designed for the population of the Republic of Moldova. The essence of sustainable development is the “ability to satisfy the needs of the present generation without compromising the opportunity to satisfy their needs”, which serves as a basis for development leading to prosperity and progress provided that resources are recycled, the environment is protected and moral rules are observed. The most important external factors that affect the health of the population are living conditions, the state of living conditions, the state of the environment and the level of medical care. This confirms the importance of ecological, social, economic and psychological factors for the generation and preservation of health.
