It is necessary to teach ecological culture from early childhood, even before school. Specialists of our territorial administrations regularly conduct eco-lessons to teach children a responsible attitude to nature. Representatives of the Kama Territorial Administration of the Ministry of Ecology and Natural Resources of the Republic of Tatarstan held a visual environmental lesson for pupils of kindergarten No. 66 "Funny Notes" in Naberezhnye Chelny and demonstrated the capabilities of a mobile ecological laboratory. Environmentalists told what factors affect air pollution, how the mobile environmental laboratory works and answered the questions of young "whyers". Now the children know "What is a laboratory?", "What is air for?" and "What can be done to make it cleaner." In memory of the lesson, the kids received gifts from the Ministry – coloring pages "School of Ecology".
