Ever heard of the "Finagle's corollary to Murphy's Law" that states that, "Anything that can go wrong, willa -- at the worst possible moment?" In our world of more than 7 billion people who reside on the planet Earth, natural disasters are a big part of our lives, some more than others. Of the seven main natural phenomena that result in disaster (Hurricanes, Earthquakes, Floods, Tsunamis, Volcanic Eruptions, Landslides) wildfires can be one of deadliest. A wildfires are uncontrolled fires, which is why they are so dangerous. Often wildfires occur in uncultivated, unpopulated areas, however, they can occur anywhere and destroy homes, agriculture, humans, and animals in their path(dosomething.org). An average of 116,000 burned 4 million acres of U.S. woodland burn per year between 1988-1997( Omi). Furthermore, in 2004, wildfires burned more than 8 million acres in 40 States(USGS). Although a wildfire can be a horrific scene of destruction some organisms(plants and animals) benefit from them. In this brief essay I would like to cover three main concerns that involve wildfires: (1) What is a wildfire and it’s chemistry makeup, (2) What causes wildfires and where do they typically take place,(3) After a wildfire occurs, what impact does it have on the environment, advantages and disadvantages.
Firstly a wildfire, which is commonly known as a wild-land fire, forest fire, vegetation fire, grass fire, peat fire, bushfire (in Australia), or hill fire, are, as stated earlier, uncontrollable fires that can accrue anywhere. Fire particularly is a chemical reaction, called combustion(nps.gov). According to environmental historian Stephen J. Payne the fundamental chemistry of combustion lies at the core of the living world; that when it happ...

It is so sad to see the horror of forest fires and how they corrupt our beautiful land. So much damage comes out of what started so small. At least 603 square miles of land were burned in the early stages of the Arizona fire only a couple of years ago (BBC 2). In a Colorado fire 2.3 million acres had been burned (BBC 3). That land could have been saved if the use of prescribed burns had been in the area.
The ecological effects of wildfires on Yosemite are among some its greatest benefits. Trees like Bishop Pines and Sequoias have evolved in such a way that their seeds will only open when exposed to high temperatures. The fires also help to clear out dead leaves and weeds, thereby making sunlight accessible to new plants and increasing their chances to germinate (Marder). Wildfires are so essential in areas like Yosemite that over millions of years, plants have developed strategies to be successful in this type of environment. For instance, giant sequoias have developed a thick layer of fire-resistant bark. This bark is “the main explanation for tree survival in intense fires” (Gignoux, Colbert, and Menaut). Fire makes the soil fertile and redistributes the nutrients evenly so that the next generation of trees can cover more space. The fires have helped...
Australia is currently the driest continent in the world and has a vast history of fire to prove it. Bushfires in the Adelaide Hills were first described and recorded in 1827, and have occurred at frequent intervals since that time. Fire weather can reach extremes in places such as Rudall River National Park in NW Western Australia. Temperatures are often above 40 degrees Celsius (104 degrees Fahrenheit), dew points can drop to —37 degrees Celsius, and the winds, uninhibited by trees, can reach speeds of 50-60 km/h (31-37 mph) at any given time in the year. The fuels there may appear to be completely dead, and gaps between plants may be a meter or more (Gill, 1995). In 1966 a massive fire at Brooyar, Queensland had flame heights of 20-25 meters (65-82 feet). In addition to being devastating, the fires are also very unpredictable. A bushfire in the Baulkham Hills in January of 1975 completely destroyed property and some homes, while leaving others untouched. Serious fires occur in the Dandenog Ranges at frequent intervals, and housing there has always been a difficult problem with fire control [3]. Fire has also been used for centuries as an important tool for land management (O’Neill, 1993).

Policies regarding the handling of wildland fires continue to change and evolve as new information is learned each fire season. Attitudes have changed between complete wildland fire suppression to no suppression at all. We now seem to have reached a balance between the two schools of thought and fall somewhere in the middle.
The Little Missouri River eroding the mountain range is the reason that the park is as it looks today. The park is believed to be <60 million years old. Over 60 million years ago volcanos all over the west were erupting and spitting out amounts of ash. The rivers near the volcanos were gathering. The rivers began to dry out, leveeing the ash behind. The ash was being dried in layers and turned into sandstone, siltstone and mudstone while the ash layers became bentonite clay. This Bentonite clay is dangerous because it gets people stuck, like quick sand it is located throughout the park. It can pull the car tires un...
Every year, over nine million hikers and adventure seekers travel to the Great Smoky Mountains National Park making it the most visited national park in the United States. There are abundant reasons for this, but many popular reasons include over 150 hiking trails extending over 850 miles, a large portion of the Appalachian Trail, sightseeing, fishing, horseback riding, and bicycling. The park houses roughly ten thousand species of plants and animals with an estimated 90,000 undocumented species likely possible to be present. It is clear why there was a pressing interest in making all this land into a national park. My research was started by asking the question; how did the transformation of tourism due to the establishment of the Great Smoky Mountains National Park affect surrounding cities such as Gatlinburg and Sevier County, and in return, its effect on the popularity of the park?

As people of the twenty-first century, we are all too familiar with the frequent occurrence of wildfires in our nation’s forests. Each year millions of acres of woodlands are destroyed in brutal scorches. It has been estimated that 190 million acres of rangelands in the United States are highly susceptible to catastrophic fires (www.doi.gov/initiatives/forest.html.). About a third of these high-risk forests are located in California (www.sfgate.com). These uncontrollable blazes not only consume our beautiful forests but also the wildlife, our homes and often the lives of those who fight the wildfires. The frequency of these devastating fires has been increasing over the years. In fact, in the years 2000 and 2002, it has been reported that the United States has faced its worst two years in fifty years for mass destruction fires (www.doi.gov/initiatives/forest.html.). The increased natural fuels buildup coupled with droughts have been a prevailing factor in contributing to our wildfires and unhealthy forests (www.blm.gov/nhp/news/releases/pages/2004/pr040303_forests.html). Due to the severity of these wildfires, several regulations and guidelines have been implemented to save our forests. In fact, the President himself has devised a plan in order to restore our forests and prevent further destruction of our woodlands.
Boom! A once ice-capped mountain peak explodes as ash fills the air. “‘Vancouver, Vancouver, this is it!’”Those were the last words of expert geologist David Johnston (Gunn 561). In 1980, Mount Saint Helens of the state of Washington erupted, filling the air with ash and causing mudflows powerful enough to lift tons. It decimated everything in its path. The eruptions, mudflows, and ash caused great damage on the landscape, yet it gave us information on how catastrophes happen and how they affect society and the surrounding landscape. The data acquired can also help us understand the way the landscape was formed. Mount Saint Helens caused much damage, but also helped people understand the science behind it.

Fire at any level can be devastating, yet the effects that wildfires have on every worldwide country really has left its mark on the land. As written by world renowned wild fire spokesperson Smokey the Bear, “Every year, wildfires sweeps through parts of the United States setting wilderness and homes ablaze. On average these raging infernos destroy about four to five million acres of land a year. But in 2012, wildfire burned more than 9.3 million acres, an area about the size of Massachusetts and Connecticut combined” (U.S. Wildfires). Destroying homes, crops, towns and of course forests. Yet the effects of these fires can be seen from a negative perspective as well as some positive. Plus there are natural causes as well as manmade that makes these destructive fires erupt and become almost unstoppable in seconds.
The Forest fire is occurring very frequently nowadays, reasons for it are a heavy increase in global warming and an increase in temperature.
