Lisbon — For three days in mid-September, wildfires rapidly tore through parts of Portugal, turning the sky a hellish, smoky red against the rolling green hills in the north. In central Portugal, a blaze engulfed a highway, cutting off the top half of the country from the bottom. Nine people were killed.

Few people in other parts of Europe and the US would have realized that some of their everyday products may have played a role in making these fires worse.
