Did You Know?

Ground-level ozone is also responsible for 1 to 2 billion dollars in reduced crop production in the U.S. each year. Because ground-level ozone interferes with the ability of plants to produce and store food, they are more susceptible to disease, insects, other pollutants, and harsh weather. Ozone also damages the foliage of trees and other plants, ruining the appearance of cities, national parks, and recreation areas.
