Millions of people worldwide who enjoy the benefits provided by cars and trucks also suffer the miseries of traffic pollution.

The device in question is the catalytic converter, which cleans gases passing through vehicles’ exhaust systems.
Engineers estimate that during the last 11 years 130 million catalytic converters used in the U.S. have eliminated automotive pollutants that-if unchecked and unabated-could have covered the country with a toxic blanket of carbon monoxide more than 500 feet deep.
