Wildfires lead to deforestation, property damage and deaths. When plants and trees are burnt away, landslides, ash flows as well as flash floods will be more likely to happen. Soil erosion may also pollute water in streams, rivers and lakes.
During drought when less than one-third of water is reserved in the soil, the plant risks drying out. When this happens, flammable gases such as ethane and ethylene may be released, and wildfires can ensue.
Most of Earth’s weather and air pollution is found in the troposphere. A severe thunderstorm in the presence of a large wildfire lifts smoke, soot and other particles to the stratosphere, which contains the ozone layer. Carbon dioxide, a greenhouse gas, can be released by the smouldering fire of the underground peat forests. |
