Dr. Shanna Swan “Sperm and Our Future”

Over the past decade, the world has become increasingly chaotic and uncertain – and so, too, has our cultural vision for the future. While the events we face now may feel unprecedented, they are rooted in much deeper patterns, which humanity has been playing out for millennia. If we take the time to understand past trends, we can also employ practices and philosophies that might counteract them –  such as focusing on kinship, intimacy, and resilience – to help pave the way for a better future. How might we nurture the foundations of a different kind of society, even while the end of our current civilization plays out around us?

For centuries, modern science has relied on the scientific method to better understand the world around us. While helpful in many contexts, the scientific method is also objective, controlled, and reductionist – often breaking down complex systems into smaller parts for analysis and isolating subjects to test hypotheses. In contrast, indigenous wisdom is deeply contextual, rooted in lived experience, and emphasizes a reciprocal, integrated relationship with the rest of the natural world, viewing all parts of the system as interconnected. What becomes possible when we combine the strengths of each of these knowledge systems as we navigate humanity’s biggest challenges? 

In this episode, Nate interviews Professor Ted Parson about solar geoengineering (specifically stratospheric aerosol injection) as a potential response to severe climate risks. They explore why humanity may need to consider deliberately cooling Earth by spraying reflective particles in the upper atmosphere, how the technology would work, as well as the risks and enormous governance challenges involved. Ted emphasizes the importance of having these difficult conversations now, so that we’re prepared for the wide range of climate possibilities in the future.
