Specialists of the Northern Territorial Administration of the Ministry told students of MBOU "Kulle-Kiminskaya OOSH" how to protect nature and preserve ecology. The eco-lesson was held in a playful way. Seventh graders discussed the relationship of man with the environment and what role nature plays in human life. The inspectors told how ecology affects the health of the population and gave advice on how to live in harmony with nature. After that guys participated in an eco-quiz.
