Recommended: Primary effects of wildfires
Over the last few years, there has been an unusual amount of devastating wildfires reported around the globe. Alaska, Indonesia, Canada, California, Spain, Portugal, and Chile have all been affected by the deadly fires. The number of deaths from wildfires has greatly increased over the last few decades. Wildfires are usually caused by careless humans or large lightning strikes. However, scientists believe that the wildfires that have recently occured have been caused by drastic climate changes. Areas have gotten hotter and drier than they have been in the past.
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.
Malibu and Yosemite share similar ecosystem, which encourages wildfires and periodic firestorms. In his book Ecology of Fear, Mike Davis argues that Malibu should burn because wildfires are a part of its history. To illustrate his point, he relates numerous historical events from the first settlement of the region to modern days. Despite the high frequency of wildfires in Malibu, humans have continued to settle there in droves. Those settlers have fought the fires, which has done nothing but augment their intensity. Unlike Malibu, with its populated areas that have been damaged by wildfires, Yosemite benefits greatly from wildfires. Yosemite’s ecosystem has evolved with wildfires; indeed, without wildfires, Yosemite would lose its uniqueness. Also, Yosemite is not as heavily populated as Malibu, so fires in Yosemite would not affect humans to the same degree that they do in Malibu.
Plants that grow in the vast arid and semi-arid regions of Australia are prone to fires simply because of the desert climate they grow in. High temperatures, low fuel moisture contents, little humidity and drying winds that sweep across the landscape encourage small patches of plants to burst into flames.
Would you believe me if I told you that many people say the Great Chicago Fire, a fire which destroyed 17,000 structures, left 100,000 people homeless, killed 300 people, and caused about $200 million in damages was the best thing that happened to Chicago? Chicago changed as a result of this fire in three ways; fire codes/laws, organization of buildings, and economic development and population growth.
Wildfires started as an annual and seasonal occurrence in the south western region of California since the early 1930’s in part because of the hot dry summers and the hot dry turbulent Santa Ana winds that blow in from the desert during the fall months. Now it has become a yearlong event (Mckay, 2010). These conditions greatly contribute to the “fire season” throughout this area. This set of circumstances in conjunction with downed power lines and humans that ignited fires took place in October of 2007. This led to a series of fires that burned more than 500,000 acres, destroyed 1,500 homes, killed 9, injured 85, and forced the successful evacuation of around 500,000 people out of harm’s way.
Virtually everywhere in the United States is affected to one degree of another by wildland fires. Even if a community is not directly involved with the fire itself, chances are that some of its members have gone to help fight wildland fires in other areas of the country by providing manpower, financial support, or other humanitarian aid.
As terrible as the Great Chicago Fire was to the city of Chicago back in 1871, the lessons learned from this disaster and the reconstruction that followed from the ashes and rubble actually helped turn Chicago into one of the great cities in the United States. This paper will examine what happened and why, what the leaders of Chicago learned from the experience, and how the will and spirit of the people of Chicago along with financial support from a sympathetic nation and beyond forever changed the city of Chicago for the better.
The reason for this is we have been having more wildfires then ever before. A big contribution to the natural disasters of this world is the ecosystem. When the air is highly polluted, the risk of things like wildfires rise. We are only raising that risk by adding more pollution to the air with prescribed fires. These fires are dangerous. They are starting to get out of control too often. By trying to reduce the risk of wildfires, we are only creating
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.
Human beings cause most wildfires, directly or indirectly. In the United States lightning, the only truly natural cause is responsible for less than 10% of all such fires. In the West, lightning is the primary cause, with smoking (cigarettes, matches, and such) the second most frequent. Combined they account for 50 to 75% of all wildfires. In the “13 southern states (Virginia to Texas) the primary cause is arson; this combined with smoking and debris burning makes up 75% of all wildfires” (Perry, 1994). The other causes of wildfires are machine use and campfires. Machine use includes railroads, logging, sawmills, and other operations using equip...
I didn 't had any trouble trying to search the internet since I had access to a computer and internet connection in my house and school. Trying to look for a source to start searching didn 't gave me trouble either since I had a list of sources in hand. The first article that I explored was called (“Wildfires”) from the National Geographic Website. In the article I learned that depending on the weather conditions wildfires can have different reactions. For example in the article they stated that “Uncontrolled blazes fueled by weather, wind, and dry underbrush, wildfires can burn acres of land and consume everything in their paths in mere minutes” (“Wildfires”). I also learned the good effects that wildfires has on the environment. “naturally occurring wildfires are fundamental in nature as they return nutrients to the soil by burning dead trees, plants, and land. They also act as disinfectant by removing poisoning plants, insects, and all soft of dangerous things” (“Wildfires”). That 's the information that I learned from the article, and while it wasn 't much I did manage to find key information. Next I visited two more websites. The first one was actually a online magazine (“Into The Wildfire”) from The New York Times Magazine. The first thing that I notice was how clean, organized, and simple this online magazine was. it did however had a big flaw, it only concentrated on the way firefighters deal with wildfires, and didn 't
The problem of Coal fires is not limited to Centralia, Pennsylvania, however. It is a problem that has caused major difficulties both in other areas of the United States (like Colorado) and also other parts of the world. In Indonesia, for instance, a series of forest fires in 1982 ignited a series of coal fires, 106 of which the government was able to extinguish, leaving 159 that are still raging to this very day. (Amos) A coal fire in Jharia, India, that had already caused the government to relocate the town’s population, destroyed a riverbank, unleashing a rush of water in the underground mines that drowned 78 coal workers. By some estimates, fires that rage in the northern coal belt of China burn something like 200 million tons of coal each year. (Krajick)
...r it is arson, an uncontrolled camp fire, or a cigarette butt it doesn’t take much for humans to spark a disaster. Yet there is as well a few set by good old Mother Nature. On top of the effects on the earth as well as humans, there is only one thing we all can do and that is listen to our old pal Smokey the Bear when he says, “only you can prevent wildfire.”
The Forest fire is occurring very frequently nowadays, reasons for it are a heavy increase in global warming and an increase in temperature.
Wildfires are catastrophic disasters that destroy everything in their path. “A wildfire (also known as forest fire, grass fire, vegetation fire, etc) is an uncontrolled fire often occurring in wild land areas, but which can also consume houses or agricultural resources.” (Wildfire.) The causes of wildfires are mostly intentional, negligence or accidents and natural causes. Wildfires have three distinct phases: Initiation, propagation, and extinction. This phenomenon affects our ecosystem, such as air and earth. In addition, people who witness this kind of catastrophe in the lower cases they lose belongings as houses or cars, but they can also lose their lives. There are many campaigns that help prevent these phenomena, but they need the help of the entire community. It is very important take care of not cause an accident. Wildfire is a phenomenon very common on these days causing a terrible damage to our environment and we have to prevent its expansion through our help, cooperation and prudence...
