Wildfire

A wildfire is an unforeseen fire that destroys natural habitats such as forests, grasslands, and prairies. These types of fires are usually unplanned.

Causes:

Lightning strikes, such as those caused by wildfires, can happen naturally, or sparks can be created by humans. The weather, however, is often the determining

factor in how much a wildfire grows. Trees, shrubs, fallen leaves, and limbs can all be dried by the wind, high temperatures, and little rainfall, which in turn could result in fire. Flames burn uphill faster than downhill, so topography plays a crucial role, too.

Effects:

  • During times of drought and high winds, wildfires increase in risk. Wildfires can disrupt transportation, communication, power and gas services, and water supplies. Moreover, they can degrade the air quality, and they can also lead to property loss, crop destruction, animal extinction, and human death.
  • Wildfires also, at the same time, impact weather and the climate by discharging large quantities of carbon dioxide, carbon monoxide and fine particulate matter into the atmosphere. This air pollution can contribute to a range of health problems, such as respiratory issues and cardiovascular ailments.
  • In addition to releasing mercury into the air, wildfires also release significant amounts of carbon monoxide into theatmosphere, which can deteriorate people of all ages’ speech, hearing, walking, muscle weakness, and vision.

According to WHO, between 1998 and 2017, 6.2 million people were impacted by wildfires and volcanic activity, and 2400 deaths from suffocation, injuries, and burns were attributed to these events globally. However, as a result of climate change, wildfire magnitude and frequency are increasing. Wildfire risk is rising as a result of ecosystems becoming drier and hotter conditions. Because they release significant amounts of carbon dioxide, carbon monoxide, and fine particulate matter into the atmosphere, wildfires also have an immediate impact on weather and climate. Health concerns like respiratory and cardiovascular disorders can result from the resulting air pollution. The impact of wildfires on mental health and psychosocial wellbeing is another important aspect of health.
