The work focuses on the concept of symbiosis in nature, particularly examining the cooperative relationships between different species of animals and plants. Bölsche explores how these "protective and defensive alliances" manifest in the natural world, supported by numerous illustrations and examples from scientific research. The opening of the book introduces the topic of symbiosis through discussions of historical figures such as Anton de Bary, who contributed significantly to the understanding of mutualistic relationships in biology. It highlights various instances of organism collaborations—like the relationship between insects and flowers or the complex interactions between marine species. The narrative emphasizes that these relationships can range from parasitic to mutualistic, with an overarching theme that even in a world often characterized by competition and struggle, peaceful coexistence can flourish through complex interdependencies.
