The earth is our common home, which must be protected and taken care of. Inspectors of the South-East of Tatarstan told what needs to be done for this. Environmentalists held a lesson for students in grades 4-5 of the Nurlat boarding school. Venera Mingaleeva, a specialist of the Southeastern TA, introduced the children to the diversity of flora and fauna of the local forests. After the lecture, the children started practicing and played the eco-game "This land is yours and mine". All participants managed the tasks and passed all the stages of the game: "Vegetable", "These funny animals", "Ecological", "My land" and the blitz tournament "Do you know ...". At the end of the lesson, each student received an environmental book.
