We inhabit a planet adorned with magnificent evergreen forests, vast sandy deserts, picturesque rolling steppes, and mysterious swampy tundra. Some parts of the Earth experience extreme heat, contrasting sharply with those that are freezing. For example, in the African deserts, the daytime temperature often exceeds +40°C, while in Antarctica, where the surface is covered with kilometer-long layers of ice all year round, the temperature drops to 50 degrees below zero. All these differences are caused by different climatic conditions in different zones of our planet. This book is about the diverse life on Earth, including plants and animals in various environments such as mountains, water, deserts, glaciers, steppes, and forests across different climate zones.
