Understanding Fire Effects on the Environment

But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide—a key greenhouse gas—into the atmosphere.

Why is fire so relaxing?

The reason we experience internal relaxation when watching a “normal” fire is, according to the researchers, because our mind is drawn into the flames, and the longer this happens, the more we let go of the jumble of every-day concerns. In this non-distracted, peaceful state, anxieties are naturally reduced.

Fire is a chemical reaction that converts a fuel and oxygen into carbon dioxide and water. It is an exothermic reaction, in other words, one that produces heat.

What is fire made of?

Most flames are made of hot gas, but some burn so hot they become plasma. The nature of a flame depends on what is being burnt. A candle flame will primarily be a mixture of hot gases (air and vaporised paraffin wax). The oxygen in the air reacts with the paraffin to produce heat, light and carbon dioxide.
