The book progresses from introducing oxygen's fundamental properties to detailing the processes driving its production, especially photosynthesis in plants. It then examines oxygen consumption through respiration and other processes. A significant portion is dedicated to factors influencing the cycle, such as deforestation and climate change.
By adopting a systems-thinking approach and using data from atmospheric monitoring and ecological studies, Oxygen Cycle provides a comprehensive overview, making it valuable for students, environmental professionals, and anyone interested in environmental sustainability.
