Everyone enjoys sitting by a fire on a cold night. Roasting marshmallows is a childhood favorite. However, burning wood is a contributing factor to the pollution in the air. As wood burns there is ash and soot that escapes from the fire pit. This only adds to the pollution in the atmosphere.
Burning garbage causes a similar problem. The materials in garbage are not always meant to be burnt. They will break down and release ash, soot, and chemicals into the air. It is best to avoid burning anything while avoiding lung infections or irritation.
