Ozone, the primary component of smog, is a gas formed when nitrogen oxide and hydrocarbons combine in sunlight. In the atmosphere, ozone occurs naturally as a thin layer that protects us from the sun's ultraviolet rays. But when it's formed at ground level, it's deadly. Lung damage from ozone polluted air is a risk faced by roughly 3 out of 5 Americans. Ozone smog is responsible for extensive damage to pines in California and in the Eastern United States. It's also to blame for crop losses in many agricultural states. As ozone diminishes in the upper atmosphere, the earth receives more ultraviolet radiation which depresses the human imune system. It will affect the well being of every person on the planet.
