Specialists of the South-Eastern Territorial Administration of the Ministry of Ecology of the Republic of Tatarstan conducted eco-lessons in kindergartens of Bugulma and Almetyevsk. Ecologists told preschoolers from Almetyevsk how to handle natural resources carefully: not to light fires in the forest, not to destroy anthills, not to pick flowers and not to catch butterflies. Experts talked with children about the cleanliness of the city of Bugulma in the kindergarten "Neposeda". The guys learned that improperly discarded household items cause great harm to nature. For example, plastic bottles will decompose from 100 to 200 years. Plastic will harm nature by releasing toxic substances. Chewing gum, which children love so much, will decompose for 30 years. The kids also learned that it is necessary to sort garbage correctly, dividing it into plastic, household waste, glass and paper. Proper disposal will help solve many environmental problems and tasks.
