Building 53 Room 4025, Highfield Campus, 4pm. All welcome. Refreshments served after the talk.
“It seems somewhat eccentric if not a little absurd to suggest that a planet is a living thing. Earth has life on it, but it’s not a biological organism. Any theory or argument which concludes that the Earth is alive could be safely filed under “not even wrong”. So when James Lovelock and Lynn Margulis first proposed the Gaia Hypothesis in the early 1970s, some seized on the possible implication that the Earth is a form of biological organism. The Earth is alive? Nonsense! In the decades since, the Gaia Hypothesis has significantly developed and been instrumental in the creation of the new discipline of Earth Systems Science which seeks to understand both the living and non-living components of the Earth in a holistic manner.
In this talk I will give an overview of some of the developments of the mathematical and conceptual theories that underpin Gaia Theory and argue why such approaches are important in a global change context. Humans are currently affecting the Earth via a spectrum of effects. While there is no danger of us destroying the Earth’s biosphere, we are at risk of nudging it into states that would be deleterious to us.”
