Read the What if . . . “Problem Molecules” box in this chapter. One such “problem molecule” when it occurs at ground level is ozone, three oxygen atoms bonded together. Ground-level ozone is formed from the action of sunlight on motor vehicle exhaust, and it irritates the eyes and lungs. Ozone occurring in the upper atmosphere (stratospheric ozone), however, is a natural and essential part of Earth’s ecosystem. Stratospheric ozone protects life on Earth from harmful ultraviolet sunlight. How can the same molecule be a problem at ground level but beneficial in the upper atmosphere? Is there anything inherent about the ozone molecule itself that makes it a problem or a benefit?
