What happen when they were no forests?

Without forests, there would be a significant loss of biodiversity as many plant and animal species rely on forests for habitat. The absence of forests would lead to soil erosion, loss of carbon sequestration, and disruption of the water cycle. Additionally, deforestation can contribute to climate change by releasing stored carbon back into the atmosphere.

What temperature will wood start a fire?

As wood is heated it first gives up its moisture. After the water boils off and its temperature is increased to 450°F. the wood particles begin evolving volatiles. Thereafter the volatiles and fixed carbon mix with oxygen and burn separately. All of the visible flames in wood fire are from combustion of the volatiles.

*****************************

It depends on the type of wood.

There is a South American hardwood (Brazilian Walnut) which is so dense, it has the same fire rating as concrete!

Parts of the beachfront boardwalk in Atlantic City has been renovated using this wood.

In 2007, a fire started under the boardwalk and tore through nearby buildings. The sections of the boardwalk with Brazilian Walnut, were left unscathed.

What is the lifecycle of a bushfire?

A bushfire typically goes through four stages: ignition (start of the fire), growth (fire spreads and intensifies), suppression (firefighters work to contain and extinguish the fire), and mop-up (final efforts to ensure no remaining hot spots). The duration of each stage can vary depending on factors like weather conditions, fuel load, and firefighting tactics.

What is being done to prevent future forest fires?

Efforts to prevent future forest fires include implementing prescribed burning to reduce fuel buildup, creating defensible spaces around communities, promoting fire-resistant building materials, and educating the public on fire safety practices. Additionally, monitoring and enforcing regulations on activities that could spark fires, such as campfires and equipment use, are crucial in preventing forest fires.

What is the red foam the planes drop on wildfires made of?

It is not foam. According to the CDF Aviation wikipedia page:

"The retardant used to slow or retard the spread of a fire is a slurry mix consisting of a chemical salt compound, water, clay or a gum-thickening agent, and a coloring agent."

Many years ago the mix contained "borates" that had a tendency to be worse than simply letting the fire burn.

Under "Aerial firefighting": "Borate salts were used in the past to fight wildfires but were found to sterilize the soil, were toxic to animals, and are now prohibited. Newer retardants use ammonium sulfate or ammonium polyphosphate with attapulgite clay thickener or diammonium phosphate with a guar gum derivative thickener." [footnotes omitted]

What is the definition for forest fires?

Forest fires, also known as wildfires, are uncontrolled fires that occur in forests or other wildlands.

Firefighters work to contain and suppress forest fires to minimize their impact.

Can the smoke from forest fires have harmful effects on people?

Yes, smoke from forest fires can contain harmful pollutants like carbon monoxide, particulate matter, and volatile organic compounds that can have adverse effects on people's health, especially those with respiratory conditions. Prolonged exposure to the smoke can lead to symptoms such as coughing, shortness of breath, and irritation of the eyes, nose, and throat. It is important to take precautions such as staying indoors and using air purifiers during periods of heavy smoke.
