Answer 2

Car pollution contributes significantly to climate change, which results from a build up of greenhouse gases in the atmosphere. Burning fossil fuels in cars releases carbon dioxide, which is the largest source of greenhouse gas emissions in the U.S. As these gases build up, they trap heat in the atmosphere, causing climate change.Car pollution also creates smog, a dangerous weather condition that reduces visibility in cities and poses a serious health threat.
