The work focuses on bringing children closer to nature, addressing the fact that children need help with building a proper relationship with nature from the earliest age. It emphasizes the importance of and the need for preschool teacher education for that process and the improvements of preschool institutions’ programs. Child upbringing requires setting up specific tasks, which must be in correlation with the child’s mental and physical abilities. The task of the preschool teacher is to adjust the process of learning about nature and playing in nature to the needs and the age of the child. Developing ecological awareness and environmental responsibility among children is one of the most basic activities of kindergarten work. The harmful effects of pollution are largely caused by the growth of industry and economy. Today, education and training for sustainable development is a fundamental and crucial field of activism and research in all aspects of contemporary global society. The need for a sustainable way of life has proven to be extremely necessary in the last decades of the 20th century. Children can build proper habits and build a quality relationship and nature through playing and games. We can raise them properly and build healthy habits. Their use of technology should be under adult supervision and time-constrained, as the child needs to be motivated for spending time in a way which would bring them closer to nature. They should be aware that excessive use of technology can have bad consequences and that spending time in nature can be fun and something we must always find the time for. The child needs to discover that nature can be protected, preserved and improved. Professional and educated preschool teachers can employ progressive practices in their work and thus improve the education system. It is an ever-changing process which grows and develops throughout the educational process.
