Preschool age is one of the most sensitive and important periods for the formation of a person's relationship with the world. It is then that a child first begins not only to get to know the environment, but also to understand his place in it. Therefore, environmental education at this stage cannot be perceived as a narrow topic about waste sorting or individual cleaning campaigns. Preschool environmental education is extremely important because a positive attitude towards nature is formed in childhood. Young children more easily acquire values and habits, therefore the development of ecological awareness already in preschool age makes sense. Children who learn to care for the environment (e.g., through waste disposal, water or energy conservation) will carry these habits into adulthood, reducing potential environmental damage in the future.
