The Natural Resources Defense Council released a map today revealing that around 127 million U.S. citizens live in areas susceptible to air quality issues (such as pollen and ozone pollution) caused by climate change.
Pollen and pollution levels are increasing due to "increasing temperatures and sunlight," as well as longer warm seasons, according to the NRDC.
The states with highest percentages of people "living in counties with both unhealthy ozone days and pollen-producing ragweed" include: D.C., Connecticut, Massachusetts, Maine, New York, Ohio, Pennsylvania, Wisconsin, Michigan, Illinois, Virginia, Colorado, Utah, and Missouri among others.
Why it matters: ragweed and ozone pollution can worsen respiratory problems like asthma and allergies, forcing people to take more sick days.
