Modern conditions in which a person lives are characterized by thoughtless consumption of natural resources, worsening the state of the environment and human health, due to the established lifestyle, needs and behavior. In order not to make environmental mistakes, not to create situations that are dangerous for health and life, a modern person should have basic ecological knowledge and a new ecological type of thinking and have a high level of ecological culture. This can be achieved only by education. Environmental education is closely related to social education, education, enlightenment, training, self-education and is aimed at developing environmental responsibility and personal qualities such as self-control, the ability to predict the immediate and distant results of their actions in the natural environment, a critical attitude towards themselves and others. Formation of environmental values of convicts in places of detention becomes one of the areas of educational work, aimed to develop responsibility for the world, instill an interest in the knowledge of nature and its interaction with society, to realize the need to protect it. The main components of the personality’s ecological culture are: human knowledge about nature, its correlations, correlations of society and nature, ways of preserving and helping the natural environment; interest in nature and the problem of its protection; positive diverse activities aimed at the preservation and multiplication of nature, decent behavior in the human environment; motifs that determine actions of children in nature (cognitive, sanitary and hygienic, aesthetic, etc.). Formation of environmental values in convicts is possible in the process of purposefully organized, resocializing, educational activities in the classroom on natural cycle subjects in secondary school, participation in thematic evenings, interactive environmental events, watching and discussing documentaries on environmental issues, visiting virtual environmental excursions, reading books and magazines about nature, preparing for holidays and participating in them as well as growing flowers , shrubs, work in the garden.
