The songbook, suitable for secondary education in grades 5 to 10, contains children's songs that critically address environmental themes. The song templates in this volume respond to the requirements of educational curricula and expand them with the topic of the environment: developing a repertoire of songs, expressing feelings and moods through movement and voice, and consciously experiencing nature and the environment.

Among the songs, "There is no Planet B" emphasizes that there is only this one Earth that must be protected—there is no Planet B. "Hot is not cool" encourages reflection on the ongoing global warming. The song "Help" addresses climate change and the threat to the environment. The song "Climate Protection instead of Climate Pollution" discusses the current situation regarding climate protection and calls for action.

"My Closet is Overflowing" deals with the handling of the latest fashion trends. The lyrics suggest reducing the purchase of new clothing through clothing swaps with friends. "Human" addresses mindful travel and encourages consideration of the necessity of air travel at least once. "Do Not Clear the Forests" highlights the importance of trees and forests as the lungs of the world. "Our Environment, Our World" discusses the current approach to climate and environmental protection, raising the children's question: "Why haven't you done more?"

"Recycling" discusses the reuse of materials with examples and the reintegration into the material and energy cycle. In addition to audio files and templates for the lyrics and notation of the songs, there are suggestions for classroom activities. The age-appropriate proposals are oriented towards the daily lives of young people. 40 pages (with notations and audio files available for download).
