Carbon is the only element in the universe with properties capable of animating every facet of the living world. Despite comprising a tiny fraction of Earth’s composition, our planet is lifeless without it. However, it has been maligned as a leading cause of climate change, reduced to an errant element and blamed as our civilization careens towards its own demise. In Carbon, Paul Hawken looks at the flow of life through the lens of carbon.

In this episode: Evonik announces changes to its North American leadership team; we look at a new plant in Weston, Michigan, for ultra-high-purity colloidal silica; and Evonik veterans in Indiana are honored by a special recognition from the Veterans of Foreign Wars.

Gases are all around us—they fill our lungs, power our movement, create stars, and warm our atmosphere. Often invisible and sometimes odorless, these ubiquitous substances are also the least understood materials in our world, and always have been. It wasn’t long ago that gases were seen as the work of ancient spirits: the sudden closing of a door after a change in airflow signaled a ghost’s presence. Scientists and engineers have struggled with their own gaseous demons.

Taking us back to that exhilarating - and often dangerous - moment when scientists tried to work out exactly what it was they'd discovered, we see gases as the formative substances of our modern world. From how nitrous oxide and chloroform get into our bloodstream and affect our neural pathways to the gases that make plants grow and flowers smell through to the carbon-fuelled climate crisis, Mark Miodownik masterfully reveals this invisible world through his unique brand of scientific storytelling.
