A recent study showed that reduced air pollution between 1993 and 2013 saved the U.S. around $24 billion a year.
The study looks at the benefits to elderly people and early deaths related to the air they breathe.
According to Gizmodo, this is the first study to examine the short-term impacts of air pollution.
For the elderly, even low levels of air pollution can increase their risk of death.
Air pollution affects people of color the most and cleaning it can have huge benefits for those communities.
