Nature in Crisis

In ‘Gaia: A New Look at Life on Earth’ (1979), James Lovelock proposed that the Earth is something like a single living organism, capable of manipulating its circumstances and the environment to suit its needs. While many scientists reject the fullest formulation of this idea, it has nonetheless had a profound influence on our understanding of the ways in which animal and plant life interact with the non-living parts of the environment, to the extent that observations in biological and earth systems science are often assessed for which version of Gaia they might support. In this episode, Meehan Crist and Peter Godfrey-Smith look at the origins of the Gaia hypothesis in the radical work of Lynn Margulis and the contributions of Lovelock’s academic collaborator Dian Hitchcock, and in the science of cybernetics. They then consider the degree to which any formulation of Gaia can explain certain processes, from the impact of the ecological competition between daisies on the reflection of solar radiation to the carbon-silicate cycle and its control of carbon dioxide levels, and consider some of Lovelock’s wilder theories, including his suggestion that humans should merge their minds with those of whales.

In Blue Machine (2024), Helen Czerski refigures the ocean as an enormous planetary engine, converting light and heat into motion. Her book invites us to see the ocean not as an ‘absence’ but an intricate series of operations that makes life as we know it possible. In this episode, Meehan Crist and Peter Godfrey-Smith reflect on the ways Czerski’s book has altered their thinking about the ocean, and whether new perspectives can ever be enough to change public policy.

After following up a lead from a birdwatcher, Rachel Carson drew a web of connections that led to one of the most influential books of the 20th century. Silent Spring (1962) investigated the synthetic pesticides that proliferated after the Second World War, which were assiduously defended by overconfident policymakers, industrial chemists and agribusiness. The book quickly became a bestseller and kickstarted the establishment of the Environmental Protection Agency. In the first episode of Nature in Crisis, Meehan Crist and Peter Godfrey-Smith discuss one of the truly great success stories in science writing. Carson was a masterful stylist and gifted scientist who could make abstruse developments in organic chemistry compelling, accessible and alarmingly intimate. Meehan and Peter show how Carson wrote at the edge of science, anticipating the study of epigenetics and endocrine disruption. They illustrate why, though some of her proposed solutions fell short, Silent Spring remains ‘both an exhilarating and melancholy pleasure’.
