How do wildfires affect air quality?

Wildfires release a significant amount of pollutants into the atmosphere, which can have detrimental effects on both human health and the environment. When vegetation burns, it produces smoke that contains a mix of harmful particles, gases, and chemicals, such as carbon monoxide, volatile organic compounds, and fine particulate matter (PM2.5). These substances can lead to respiratory problems, cardiovascular diseases, and other health issues for people exposed to them.

Furthermore, the environmental impact is wide-ranging, as air quality can deteriorate not only in the immediate vicinity of the wildfire but also in areas far downwind due to the dispersal of smoke. This can affect wildlife, ecosystems, and even contribute to climate change due to the release of greenhouse gases like carbon dioxide.

In contrast to the other options, which either downplay the role of wildfires in air quality or misrepresent their impacts, the chosen answer highlights the real and significant consequences of wildfires on the atmosphere and public health. The assertion that wildfires improve air quality or have no significant impact fails to acknowledge the well-documented effects of smoke and pollutants released during these events. Additionally, the idea that wildfires solely affect wildlife overlooks the interconnectedness of ecosystems and air quality, reinforcing why the correct answer emphasizes the harmful
