What is Smog?
Smog is a form of air pollution. Air pollution is defined as any change in the atmosphere that has harmful effects. Substances that cause pollution are called pollutants. Smog is a pollutant that creates a brown and very dirty haze over an area.
Where Does it Come From?
Smog is formed when gases in the air react with sunlight. The gases that form smog usually come from a car's exhaust. This is a major problem because in society we use cars as the main source of transportation.
What are the Harmful Effects?
When the smog levels are very high, you will start to see some severe effects. Since smog is as gas, it can cover a large area with thick pollutants. Similar to air, it can get into your eyes, throat and lungs. Effects could be a burning sensation in your eyes, breathing trouble, and irritation in your throat or lungs.

Is There a Solution?
There are many ways to reduce the threat of smog, but they are not used enough to make a difference and that is the problem. Any idea that reduces the amount of car use such as, bicycles, carpools, and mass transportation, are a solution. Technology like catalytic converters are also useful. Catalytic converters take exhaust from a car and convert it into a less harmful gas. This reduces the amount of gases that smog will form from.
