The article describes the views of Abu Ali ibn Sino, a great thinker of the Middle Ages, on environmental problems. His scientific approaches to areas such as environmental hygiene, water and air pollution are analyzed. Nature is a place where all living things can live. According to him, nature is a single, whole, in which opposite aspects such as matter and form, movement and peace, cause and effect are interconnected and interact. A violation of such a relationship can have negative consequences on earth. We can see this in the example of the environmental problem, which is recognized as a global problem today.We know that a person has been wounded, that the environmental problem has been on his mind. We can see this in the works of our great compatriot, encyclopedist Abu Ali Ibn Sino. What we call environmental problems today, issues of protecting the environment, the impact of man on nature or man on the environment are often mentioned in Ibn Sino’s works. Especially his thoughts that “Agar havoda chang va tutun bo’lmaganda edi inson ming yil yashagan bo’lur edi”, “If the air is balanced and clean, without foreign additives, it will be a guarantee of health, otherwise it will cause various diseases” confirms the existence of environmental problems before.
