Discover Earth's invisible systems and transform your understanding of the world

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.

Skip to 0 minutes and 8 seconds [BREATHING] We take 20 thousand breaths a day To extract the oxygen from the air that we need to live. Wake up the next morning, the oxygen’s still there. There’s an invisible world A life support system which gives us this clean air, fresh water, fertile soil, rich biodiversity, a stable climate, and a phenomenal recycling system. I’m Professor Tim Lenton, from the University of Exeter. And I’m Dr Jo Elworthy from the Eden Project. And together, we’re going to be teaching you about the incredible Invisible Worlds that provide this life support system for us.

Skip to 0 minutes and 46 seconds Invisible Worlds is also an exhibition here at the Eden Project, where scientists like myself work with communicators, artists, designers, writers to bring those Invisible Worlds to our senses and to explore a fresh perspective on our life support system. Because if we are to have a flourishing future on this planet, with all the magnificent life forms that we share it with then we need to see our place in the world in a new way. We need to think about how we interact with the rest of our life support system to create a better future together.

What topics will you cover?

  • 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.
