Modern picture books play a key role in raising awareness about the conservation of endangered and protected plant and animal species. Through stories often featuring characters from nature, children are introduced to environmental protection and the importance of biodiversity preservation in an accessible and educational manner. These picture books not only provide information about specific endangered species, such as the Mediterranean monk seal, blue whale, bees, turtles, and plants like perunika and fritillary, but also encourage children to develop ecological awareness and empathy for nature. In books such as "Protect the Mediterranean Monk Seal" and "Bears from Gorski Kotar", children are introduced to the threats facing animal species, while "Perunika" and "Fritillary" present rare plant species and the challenges they face. Through imaginative and creative stories, children develop an understanding of the importance of nature conservation and learn how human actions impact the environment. Some books, such as "Tigiji and the Offended Plant Anuk" and "Green Dreams", deliver a broader message about environmental awareness and the need for responsible behavior towards nature, encouraging children to think and act sustainably. These picture books are an important educational tool, as they not only bring nature closer to children but also actively engage them in thinking about environmental protection. The combination of ecological themes, educational stories, and nature-based characters empowers children to develop a sense of responsibility towards the environment and the world around them.
