We measure carbon. We measure water. We measure materials. Almost nobody measures chemistry.

Chemical Footprint opens Season: The Chemistry of Waste. From France’s drinking water surveys and Swiss wastewater upgrades to Denmark’s groundwater, Cape Fear, and Asia’s manufacturing floors. This episode asks why modern economies still have no shared chemical footprint, and what that missing number hides.

Every molecule we make creates value. That is why we make it.

And every molecule we make leaves a trace. That is what we tend to forget.

The story of those traces is the story of The Chemistry of Waste.

New tsunami evacuation signs are appearing along the Portuguese coast. Behind them sits an entire machine: sensors, warning centres, sirens, and a national drill held every November. This episode looks at how that machine actually works, and where it stops working. Why the most dangerous wave would arrive in fifteen minutes, before any siren can help. Why Indonesia's warning system existed on paper and still failed. What a ten-hour blackout revealed about the part of resilience nobody builds. And what the schoolchildren of one Japanese city proved about the difference between having a plan and being ready.

First episode of Resilience, a new series about what keeps a society standing when the unexpected arrives.
