Given the current climate emergency, it’s increasingly important that we have a good understanding of Earth’s life support systems. We rely on these systems for fresh air, clean water, fertile soil, rich biodiversity and a stable climate.

On this course, you’ll explore the natural systems we can’t see or feel, from microscopic creatures to gases.

You’ll discover how life is shaped by and shapes these invisible worlds and explore the evolution of these systems and the impact humans have on it. As you explore the interconnectedness of everything, you’ll transform your understanding of the world.

• Past Invisible: A time so long ago it’s hard to imagine: the evolution of the Earth’s life support system; the products and processes that are necessary for maintaining life.
• Vast Invisible: Natural systems and cycles (carbon, nitrogen, phosphate) so massive we can’t feel them: the bigger picture and you in the bigger picture.
• Small Invisible: Creatures so small we can’t see them: minions or masters of the universe? See how the smallest things underpin the biggest things; the life support systems.
• The Anthropocene era/effect: Since the small things have such a significant influence on the life support system, you won’t be surprised to see the huge effects we have had.
• Interconnections: The interconnectedness between life and the Earth’s environments at all scales.
