Specialists of the Northern Territorial Administration of the Ministry of Ecology of the Republic of Tatarstan held an eco-lesson outdoors for students of the Forestry school of the Arsky district. During the walk, environmentalists told why it is necessary to take care of the cleanliness of reservoirs and shared simple rules for saving water. In turn, the children told about how they take care of the environment and in which environmental campaigns they take an active part. "To preserve the purity of reservoirs in the area, various events are often held, such as "Water of Russia". All classes amicably go outside and clean up. Our class loves such clean-ups very much," the guys say.
