Why the Search “Fire has been around for millions of years, but it has only been in the last 1.5 million years that humans have figured out how use it” (“Facts”). I always have wondered why fire is the only element that isn 't friendly with the human specie. For example, water, earth, and air all have harmless entities that species can safely have direct contact with. Fishes live in water, and people live on land. However, there are no species on this planet that can have direct contact with fire and not get hurt. Maybe that’s the reason that animals and people consider fire to be dangerous, especially if we 're talking about wildfires, which has a massive impact, on both people and land. But in the end, no matter how dangerous and destructive …show more content…
The Search I decided to begin my first search on the Internet. Since I had access to both a computer and an Internet connection, I had no issues in that regard. The first article that I explored was called “Wildfires,” from the National Geographic website. In the article, I learned that depending on the wind condition, wildfires can have different reactions. For example, in the article they stated that “wildfires can burn acres of land and consume everything in their paths in mere minutes” (“Wildfires”). I also learned the positive effects that wildfires has on the environment. For example, 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 poison plants, insects, and all sorts of dangerous species (“Wildfires”). That 's the information that I learned from the article, and while it wasn 't much, I did manage to find …show more content…
It was called Fundamentals of Wildland Fire Fighting by Carl Goodson. The book started by explaining the basics of each phase of fire. For example, the combustion process, which is basically the phase in which fire starts, comes first. I learned that in the Wildland both fuel and oxygen are present, but in order for the combustion process to start, heat must be added to liberate the fuel gasses. In this state, the process keeps repeating. So once the chemical combustion starts, the more heat is released from the energy, and as more heat is released, more fuel gases are liberated, which adds into more fire. However the behavior of oxygen is different, since the amount of oxygen available in the land doesn’t decrease or increase depending on the heat. It does, however, change depending on the weather’s condition, as the wind can definitely increase the oxygen that is available to the fire. Later in the book I saw a discussion of conduction, which Goodson describes happen, “when two objects of different temperatures contact with each other directly; heat transfers from the warmer to the cooler object until their temperature are equal” (17). For example, when a person touches a pot of boiling water, his or her fingers will get burned. That reaction is the conduction process. The heat of the pot transfers from the
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.
Although fire is linked to human life, as it is essential for survival, not only its use for food, security and warmth, particularly in the extreme cold weather
The Blackwater fire of 1937 was a forest fire that occurred when a lightning strike ignited a tree in the Shoshone National Forest. It lasted for 6 days and killed 15 people, injuring a further 38; David P. Godwin (investigator of the fire) said,“not since 1910 have so many lives been lost on a single national forest fire”. The fire consumed a total of 1700 acres of forest woodland1 in this time. The Blackwater fire’s dire effect therefore resulted in the methods of firefighting that were used at this time being reviewed and updated to try to make firefighting safer for those involved in combating fire.
Prescribed fire is a controlled burn of an area done by a team of experienced or educated people in a grassland or forested area. This type of burn is intended to help the health of plant and animal species and restore them to their native state. When certain areas that need to be burned so often do not get burned, they can be a hazard to the ecosystem in which it presides. A forest can get over grown and thick which will create more fuel for a wildfire that can destroy a forest community. In grassland a controlled burn, or prescribed burn, can help eliminate invasive species that can take over grasslands that are harmful to the more desirable plants. This type of fire can be seen as harmful and a disaster by many people, but it has great benefits on the areas in which it is done.
Forest fires kill many animals and usually destroy a large amount of land. Prescribed burns seem like they would be the best idea, but are they? Their claim to fame is to clear out land in order to decrease the burning space for when an actual forest fire occurs. Yet this may seem like a brilliant idea, but one must look at the negative aspects of controlled burnings. People might have a change of heart when they realize the damages and effects of such an interesting act. Keep in mind that not only is your health involved but even such things as the inconvenience of dealing with a smoky town. It is important to understand that prescribed burns cause severe health problems especially to firefighters; these are concerning carbon monoxide poisoning, visibility issues and health risks that will affect the future.
The statement “Killing 150,000 people in less than a second actually allowed fewer lives to be lost.” might sound horrendous. However, that statement is the reason why the United States was able to win the Second World War. In contrast to this statement, some people might argue that it is inhumane to massacre that many people in less than a second. The dropping of the atomic bombs on August sixth and ninth of 1945 was the correct decision for American in order to effectively and efficiently end World War Two. America should have dropped the bomb because it saved American lives, there was a lack of incentives not to use the bomb, and dropping the bombs was the quickest way to end the war.
Words have so many different meanings. Just pick up a dictionary to discover the many different meanings of the same word. Have you ever wondered where the meaning of the word originated? Maybe you have asked what a word means when another has used it out of context. How did one word come to mean so many different things? This paper will allow me to explore the definition of burn and where it originated. I will also discover how it has changed over the years and what the definition is today.
Altho somewhat similar the two stories are very different in many ways. The first story is called “Mystery of Heroism” by Stephen Crane and the other one is “To Build a Fire” by Jack London. Both of the books are part of the short story genre and realism stories. The author's purpose for writing the “Mystery of Heroism” is to tell a story about a brave man who went to get water for a dying man. The purpose for writing “To Build a Fire” is to tell about a man and his dog and how he tried to fight the below freezing temperatures to stay alive. Both authors use realism because they want to tell real stories about people and how they had to overcome struggles in their lifetime. These two stories have similarities but they are way more different than anything else. One of the stories is about a man who has to overcome fear to get water for a man.
Prescribed fires are a well debated topic. While many people support them because they "help prevent" more wildfires, and they are "controlled," I see from a different point of view. There's a reason most building don't allow smoking within a certain distance of the building. Many people don't like it and it can damage their health. Same thing with prescribed fires. They add more pollution to the air we breathe. I know a lot of people support these kinds of fires because the help control fuels, but there are other ways.
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...
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.
Combustion occurs when any organic material is reacted or burned in the presence of oxygen to give off the products of carbon dioxide and water and energy. The organic material can be any fossil fuel such as natural gas (methane), oil, or coal. Other organic materials that combust are wood, paper, plastics, and cloth. The whole purpose of both processes is to convert chemical energy into other forms of energy such as heat.
The day school dismissal time is at 2:40 p.m. and students in grades K-3 are dismissed in the school yard and students in grades 4-5 are dismissed out of doors exits A and B onto Chauncey Street. I have a total of seven groups and I have one teacher’s assistant group per grade K, 1st, and 2nd, 3rd pick up students from the school yard to escort participants to the cafeteria for a snack. Two teachers for grades 4 and 5 standing at the exits A and B to escort the students to the cafeteria. I have a total of 8 staff members in the school building by 2:30 p.m. and is at their designated post no later than 2:38 p.m.
One of the biggest problems that people are faced with on a day-to-day basis is cigarette smoke. The sole cause for 480,000 deaths each year just in the United States is accredit to cigarettes(CDC). For a lot of the smokers the habit of smoking happens to assist them when under stress and dealing with issues that are unmanageable. Some smoke to appeal to their peers or simply because it “feels good.” Smoking one cigarette can lead to a major addiction. The effects of smoking hurt oneself and those amongst us. Smoking Kills as the ad portrays this revolver and cigarettes as the bullets, and also lists the side effects of smoking. Cigarettes causes cancer, increases the risk of you getting a stroke, highly addictive and causes a lot of health problems. Nearly 16
Obliterating everything in its path, a bushfire is a natural hazard, which can be defined as wild fires in scrublands and or bushlands, especially one that spreads rapidly and is hard to contain. They can be catastrophic, causing severe damage to properties, the environment and even deaths. And as a result there is an ever-increasing need to prepare for the potential impacts of bushfires.
