This free online course will teach you how microbiomes regulate ecosystems and influence human and environmental health.

What if the smallest organisms on Earth held the biggest answers to climate change and human health? This course dives into the fascinating world of environmental microbiomes, revealing how microbes drive nutrient cycles across ecosystems. It addresses a pressing challenge: understanding the hidden links between soil, oceans, and the human body. With growing environmental shifts, this knowledge is no longer optional; it is essential for shaping a healthier planet.

You will explore how gut and soil microbiomes influence ecosystem stability and human wellbeing, uncovering surprising similarities in their function. The course also examines nitrogen deposition and carbon sequestration, and their roles in climate change, through a human health lens. By connecting ecology with health science, it builds a powerful, multidisciplinary perspective that today’s learners and professionals need to stay relevant.

The journey continues into ocean ecosystems, where microbial life supports marine biodiversity and global nutrient cycles. You will learn how environmental changes disrupt these delicate systems and how host-microbiome relationships shift under stress. With real-world insights and cutting-edge research approaches, this course equips you to understand and respond to one of the most urgent scientific challenges of our time.
