Climate change is undisputed, but how do we deal with carbon dioxide, which is considered the scapegoat for global warming? This book offers a critical look at CO₂ and its role in the current climate debate. It sheds light on the influence of agriculture and forestry, the importance of tree species selection in afforestation, the challenges of using biogas and hydrogen, and questions the role of fossil fuels. You will learn how forest fires and land use affect the climate and which methods can actually help reduce CO₂. It also shows why CO₂ should be seen not only as an environmental problem, but also as an essential component for life on Earth. A guide for anyone who wants to understand the complex relationship between CO₂ and our planet.
