What is Smog?
Smog exists where emissions exist, even if you don't always see it.
Smog is a form of air pollution resulting from the interaction of UV sunlight with chemicals in the atmosphere like nitrogen oxides that get into the air primarily from the burning of fuel (ex. vehicle emissions).
As a gas, smog is easily inhaled, making it extremely hazardous to humans and animals, and can lead to severe health risks including lung tissue damage, bronchial infections, and heart problems.
