Aug 5, 2022 · Image 2: Hectares of forests lost to wildfires, 2021 Large-scale and intense wildfires like the ones that occurred in Australia can have other indirect health impacts, due to smoke and other particulate matter, leading to respiratory issues such as asthma, bronchitis, reduced lung function, as well as skin problems, eye irritation, and in some cases even premature death.
Jan 1, 2024 · This includes the demise of soil cohesiveness due to heat, which in turn speeds up soil erosion through rain and wind, the destruction of the intricate the environment resulting in an important effect on ecosystems (Roy et al., 2022), resulting in the release of greenhouse gases (GHG) and forest fires account for 17.5% of worldwide emissions of greenhouse gases (Bakır et al., 2022).
- Wildfires Can Create Hazardous Air. As the recent fires in Quebec illustrated, wildfires can have far-reaching impacts on air quality, with wind pushing smoke across hundreds of miles and causing widespread health hazards.
- Wildfires Fuel Climate Change. In addition to creating poor air quality, wildfires produce planet-warming greenhouse gases that fuel climate change. Because trees store carbon, they also release it into the air as they burn.
- Wildfires Threaten Water Security. Forests are vitally important for safeguarding water quality and freshwater access. Forested watersheds provide over two-thirds of the world’s drinking water, with 33 of the world’s 105 largest cities relying on forested areas for their water supplies alongside many smaller cities and rural regions.
- Wildfires Can Increase the Risk of Flooding. Cities are especially susceptible to flooding. Urban areas have high amounts of impermeable surfaces, such as sidewalks and roads, which results in more runoff when it rains.
Jul 10, 2022 · How Do Wildfires Begin? Before understanding the effects on the environment, we must know where the wildfires come from. Based on the survey by who.int, 50% of the causes of wildfires events are unknown. The primary cause of the wildfires is lightning — especially the long-lasting hot lightning bolts.
High-severity fires burn with high heat, climb into and remove the tree canopy, and can scorch the soil and tree roots. At a large scale, high-severity fires can be incredibly damaging to wildlife and the ecosystem. Mosaic fires are a mix of mostly low-intensity fire with patches of high- and moderate-severity fire and some unburned forest.
