Can skyscrapers be made safer, more efficient, and livable in our rapidly growing cities? Skyscrapers are gleaming symbols of prestige, and an ingenious way to save space in dense urban areas. But as buildings rise ever higher, what are the risks of these architectural behemoths?
Do we truly know how they will hold up in earthquakes, fires and wind? What have--or haven’t—we learned from past tragedies? But even as we devise ways to defend them against potential disasters, can we also make them more livable, interactive, and eco-friendly?

Scientists and engineers fight to save Notre Dame Cathedral after the 2019 fire. When the roof of Notre Dame Cathedral erupted in flames in April of 2019, firefighters battled for nine gruelling hours to save the historic landmark. Still, Paris came alarmingly close to losing more than 800 years of history. Now engineers are in a different race against time: to rebuild the roof and secure the medieval structure of Notre Dame. Underneath the charred scaffolding and vaulted ceilings of the cathedral, scientists study the components of Notre Dame’s iconic structure to puzzle out how best to repair it.

And the other surrounds us, hiding in plain sight — a world that the oil and gas companies don’t want the rest of us to see. Using covert tactics and state-of-the-art technology, the Racing Extinction team exposes these two worlds in an inspiring affirmation to preserve life as we know it.
