This course invites you to discover the remarkable chemical processes that shape our planet and sustain life. It explores the fundamental chemistry of Earth’s natural systems, from the composition of the atmosphere and the cycling of elements in soils and oceans to the molecular interactions that determine biodiversity and the resilience of ecosystems. You will study how chemical principles govern nutrient balance, mineral formation, and the complex network of biochemical reactions in living organisms. By understanding the chemistry inherent in nature, you will gain insight into the delicate boundaries that maintain the Earth’s stability and learn how human activities can align with these natural processes rather than disrupt them.
