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.

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.

How does a mere molecule—a chemical structure—become a drug? And how do we know that it works safely?
