Wildfire is a part of nature. ... 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.
How are wildfires good and bad for the environment?

This allows important nutrients to return to the soil, enabling a new healthy beginning for plants and animals. Fires also play an important role in the reproduction of some plants.
How does California wildfires affect the environment?
The removal of natural fire from an ecosystem can lead to excess fuel buildup and changes in vegetation composition , which can increase the risk of uncharacteristically large high-severity fires. ... Expanded areas of high-severity fire can impact tree regeneration, soil erosion, and water quality.
What are two effects of wildfires 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.
What are the negative effects of wildfires?
Wildfires increase air pollution in surrounding areas and can affect regional air quality. The effects of smoke from wildfires can range from eye and respiratory tract irritation to more serious disorders, including reduced lung function, bronchitis, exacerbation of asthma and heart failure, and premature death .
What are the positive effects of wildfires?
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil . Reducing this competition for nutrients allows established trees to grow stronger and healthier. History teaches us that hundreds of years ago forests had fewer, yet larger, healthier trees.

Does fire smoke pollute the air?
Smoke isn’t your ordinary air pollution . ... When a fuel burns, whether it’s gas or vegetation, it sends these fine particles up into the air and sometimes into our bodies. Fine particles from wildfire smoke led to 10 percent more respiratory hospitalizations than there would be without the smoke, the study found.
What are the long term effects of wildfires?
