As homes, businesses and cars — and the products within them — were incinerated, gases, chemicals, asbestos and other toxic pollutants were released into the air, often settling into soil and dust.

But even after crews cleared rubble and debris from their property, they are wary to rebuild without confirming whether lingering pollutants may still be in the soil.

“Those who call carbon a pollutant might want to lay down their word processor,” Hawken writes.
