Wildfires: Causes and Consequences!

By John C. Barnard Last updated Apr 28, 2022 0

Wildfires are uncontrolled, rapidly expanding, and roaring massive flames aided by wind and firebrands that can obliterate an entire forest or vegetation land area in minutes. Wildfires are one of nature’s most destructive forces, wreaking havoc on both humanity and the environment.

Every year, more than 700 wildfires burn down about 7 million acres of land and destroy more than 26,000 structures, according to the United States Fire Service. Each year, central and local groups collaborate to put out tens of thousands of fires. Each year, the United States spends more than $5 billion fighting fires.

This money will be used to pay a brigade of firefighting troops, which will include the use of airplanes to drop water on fires, phosphate fertilizer to delay the growth of fires, and trucks to cut off the spread of fire.

Depending on the type of vegetation burned, wildfires are also known as bushfires, forest fires, woodland fires, grass fires, vegetation fires, and peat fires. In the wildlands, they are unwelcome, unpredictable, and uncontrolled fires.

Wildfires can reach temperatures of over 2,000 degrees Fahrenheit in extreme cases. That temperature is double that of Venus’s surface.

Wildfires can reach 50 meters in height with their flames. Wildfires can become so large that they alter local weather patterns. They also spread quickly on the ground, running twice as fast as a person. That said, it’s really tough to put a halt to anything like that.

Some of the causes and impacts of wildfires are listed here.

Wildfires’ Primary Causes

Three things are required for a fire to start: oxygen, heat, and fuel. This is referred to as the fire triangle by foresters. Fire will spread in the direction where one of these ingredients is abundant. As a result, the only way to put it out or regulate it is to severely restrict one of these three factors. The following are the primary causes of wildfires, which annually destroy thousands of hectares of land:

Human Factors

Humans are responsible for 90% of all wildfires. Every year, reckless human actions such as leaving campfires unattended and improperly dumping cigarette butts result in wildfire tragedies. Other significant sources of wildfires include accidents, purposeful acts of arson, debris burning, and fireworks. The human causes of wildfires are thorough elaborations below.

Smoking: According to a global survey of smoking-related fires conducted by epidemiologists, smoking is the greatest cause of fires and mortality worldwide. According to the research, the global cost of these fires in 1998 was projected to be $27.2 billion.

The cost of wildfires in the United States was predicted to be $7 billion in the same year. People have an uncontrollable habit of smoking while driving, walking, or biking, and then discarding the cigarette butt without totally extinguishing it. After smoking, smokers are sometimes forgetful about extinguishing cigarette butts.

Occasionally, cigarette buds are not properly extinguished before being discarded. These people have no idea where those buds will wind up, and the majority of them cause fires.

This is why smokers should abstain from these unhealthy practices or ensure that the buds are properly extinguished before discarding them. This type of irresponsibility is what causes wildfire tragedies in many locations since a cigarette butt can start a fire.

Unattended Campfires: Camping is a fascinating experience, and I’m sure most people enjoy it as a way to connect with nature and spend time outside. During camping or other outdoor activities, however, individuals frequently leave lit fires or combustible materials unattended, which can result in wildfires. To avoid wildfire disasters, all lighted fires and combustible objects must be completely extinguished after usage.

Between 2006 and 2015, humans were responsible for about half of the 73,110 wildfires in the United States. Campfires were responsible for one-third of the 33,700 human-caused wildfires during that time period. More than 1.2 million acres of land were destroyed by the wildfires.

These data demonstrate how easily a campfire can start a large wildfire. Camping has become more popular in recent years. Individuals, both young and old, want to get away from the crowded, polluting cities and their environs to spend quality time in the woods and experience nature’s beauty.

When the weather cools down when camping, you’ll need a fire. If not properly extinguished, a campfire can spark a wildfire.

Burning Debris: Wastes and trash have been burned to ashes on various occasions in order to reduce the accumulation of garbage. After the waste or rubbish has been burned, debris remains, which burns slowly. Because of the heat, this slow-burning material has the ability to set anything ablaze and create a wildfire.

Burning rubbish to get rid of junk, refuse, and yard waste is prevalent in isolated regions. The burning of such waste is generally permitted in most locations.

As a result, many individuals see burning debris as the first option when it accumulates. However, in rare cases, these fires expand and overcome the individuals, resulting in major fire breakouts.

Some governments have intervened to help alleviate the problem by requiring people to get burn permits before burning any debris.

Humans utilize fireworks for a variety of reasons, including festivities, transmitting signals, and illuminating locations. Birthdays, Christmas, and New Year’s Eve are all occasions for spectacular festivities, complete with fireworks.

Their explosive nature, on the other hand, has the potential to start wildfires. A single wayward spark can ignite a massive wildfire, destroying hundreds of acres and causing significant injuries.

Furthermore, due to their slow rate of combustion, the residual fragments may fall into unanticipated locations, causing a wildfire. In the United States, fireworks ignited 57 fires in the state of Nebraska in 2016, resulting in $285,365 in losses.

As a result, it’s vital to understand the explosive nature of fireworks and their enormous potential to start catastrophic wildfires if they’re set off in the wrong places.

Accidents involving types of machinery, such as gas balloon explosions and car crashes, can start wildfires. If the machines are operating within or next to forest or bush areas, hot and explosive sparks from machinery accidents or engines can start massive forest or brush fires.

When space heaters malfunction, they can lead to electric fires in houses, such as old outdated equipment, faulty electric outlets, extension cords, and outdated wiring. Electric appliances that go awry cause 28,600 fires each year, according to the US Fire Administration. Most are unintentional, but if not detected quickly, they can cause large wildfires. Wildfires can also be started by lawnmowers, car accidents, and gas balloons.

Arson: Some persons may set fire to land, houses, or other things with the goal of destroying it. About 30% of all wildfires are caused by somebody intentionally setting fire on their own property.

An arsonist is a person who commits such a horrific crime. Arson experts have confirmed that arsonists are responsible for a large number of fires, accounting for roughly 30% of all wildfire incidents.

As a result, arson has a significant impact on the likelihood of wildfires, which can only be averted if people refrain from such heinous acts. Arsonists must be reported to the appropriate authorities as soon as they are discovered.

Natural Factors

About 10% of all wildfires are caused by natural sources. Natural-caused wildfires, on the other hand, differ from one place to the next, depending on vegetation, weather, climate, and topography. Lightning and volcanic eruptions are the only two significant natural sources.

Lightning: Lightning is responsible for a large number of wildfires. Although it may be tough to accept this fact, experts have discovered that it is a common trigger. A spark can be created by a lightning strike. Lightning can strike electricity cables, trees, rocks, and other objects, causing a fire.

Hot lightning is the type of lightning linked with wildfires. It has lower voltage currents, but it strikes more frequently and for longer periods of time. As a result, fires are usually started by persistent hot lightning bolts striking rocks, trees, electrical lines, or anything else that could start a fire.

Volcanic eruption: During a volcanic eruption, hot magma in the earth’s crusts is frequently ejected as lava. The molten lava then pours into neighboring fields or lands, causing flames to erupt.
