The Origin of Wildfires and How They Are Caused

The Origin of Wildfires and How They Are Caused It is interesting to note that, of the four billion years of earths existence, conditions were not conducive for spontaneous wildfire until the last 400 million years. A naturally-occurring atmospheric fire did not have the chemical elements available until major several earth changes occurred. The earliest life forms emerged without needing oxygen (anaerobic organisms) to live about 3.5 billion years ago and lived in a carbon dioxide based atmosphere. Life forms that needed oxygen in small amounts (aerobic) came much later in the form of photosynthesizing blue-green algae and ultimately changed the earths atmospheric balance toward oxygen and away from carbon dioxide (co2). Photosynthesis increasingly dominated earths biology by initially creating and continuously increasing the earths percentage of oxygen in the air. Green plant growth then exploded and aerobic respiration became the biologic catalyst for terrestrial life. Around 600 million years ago and during the Paleozoic, conditions for natural combustion started developing with increasing speed. Wildfire Chemistry Fire needs fuel, oxygen, and heat to ignite and spread. Wherever forests grow, the fuel for forest fires is provided mainly by continued biomass production along with the resulting fuel load  of that vegetative growth. Oxygen is created in abundance by the photosynthesizing process of living green organisms so it is all around us in the air. All that is needed then is a source of heat to provide the exact chemistry combinations for a flame. When these natural combustibles (in the form of wood, leaves, brush) reach 572 º, gas in the steam given off reacts with oxygen to reach its flash point with a burst of flame. This flame then preheats surrounding fuels. In turn, other fuels heat up and the fire grows and spreads. If this spreading process is not controlled, you have a wildfire or uncontrolled forest fire. Depending on the geographic condition of the site and the vegetative fuels present, you might call these brush fires, forest fires, sage field fires, grass fires, woods fires, peat fires, bush fires, wildland fires, or veld fires. How Do Forest Fires Start? Naturally caused forest fires are usually started by dry lightning where little to no rain accompanies a stormy weather disturbance. Lightning randomly strikes the earth an average of 100 times each second or 3 billion times every year and has caused some of the most notable wildland fire disasters  in the western United States. Most lightning strikes occur in the North American southeast and southwest. Because they often occur in isolated locations with limited access, lightning fires burn more acres than human-caused starts. The average 10-year total of U.S. wildfire acres burned and caused by humans is 1.9 million acres where  2.1 million acres burned are lightning-caused. Still, human fire activity is the primary cause of wildfires, with nearly ten times the start rate of natural starts. Most of these human-caused fires are accidental, usually caused by carelessness or inattention by campers, hikers, or others traveling through wildland or by debris and garbage burners. Some are intentionally set by arsonists. Some human-caused fires are started to reduce heavy fuel buildup and used as a forest management tool. This is called a controlled or prescribed burn and used for wildfire fire fuel reduction, wildlife habitat enhancement, and debris clearing. They are not included in the above statistics and ultimately reduce wildfire numbers by reducing conditions that contribute to wildfire and forest fires. How Does Wildland Fire Spread? The three primary classes of wildland fires are surface, crown, and ground fires. Each classification  intensity depends on the quantity and types of fuels involved and their moisture content. These conditions have an effect on fire intensity and will determine how fast the fire will spread. Surface fires typically burn readily but at a low intensity and partially consume the entire fuel layer while presenting little danger to mature trees and root systems. Fuel buildup over many years will increase intensity and especially when associated with drought, can become a rapidly spreading ground fire. Regular controlled fire or prescribed burning effectively reduces the fuel buildup leading to a damaging ground fire.Crown fires generally result from intense rising ground fire heat and occur in the higher sections of draping trees. The resulting ladder effect causes hot surface or ground fires to climb the fuels into the canopy. This can increase the chance for embers to blow and branches to fall into unburned areas and increase the spread the fire.Ground fires are the most infrequent type of fire but make for very intense blazes that can potentially destroy all vegetation and organic manner, leaving only bare earth. These largest fires actually create their own winds and weat her, increasing the flow of oxygen and feeding the fire.

'Motivation may be internal but it also has external social factors.' Essay

'Motivation may be internal but it also has external social factors.' Discuss this in light of the relevant theory on motivation - Essay Example Because change is important and must be dealt with in a persons life, it is important to take a look at theories of motivation. We also know that motivation may be internal but it also has external social factors. Motivation can be defined in many ways but it is basically why people do what they do. We talk about how people are motivated by food and shelter needs or because they want a good job or because they want to change their circumstances. Many people will note that self-esteem is built into the existence of motivation because you must have it in order to engage in many situations. As an example, when you achieve something you want to do it makes you feel good. At the beginning of this situation if you have a strong self-esteem, you may be motivated to do a task to get what you want. You might decide to go back to school in order to gain a degree that will move you forward in your profession. Self-esteem is important in this situation because it creates the catalyst that you will use to get to your goal. On the other side, once you have achieved your goal and received your degree, your self-esteem is at play because in feeling good, you are able to share your good fortune with others. H ence, self-esteem is very important to developing a solid place in life. No one has been able to define what motivates people though many have researched the issue. Researchers have found that there are many different ideas, thoughts or processes that motivate people and generally no two are alike. For this paper, we shall examine several theories and then examine how the theories work in social situations. There are a variety of theories that tell us why and how an individual is motivated to change. A basic theory of motivation was Abraham Maslows Hierarchy of Needs. According to Maslow (as quoted in NetMBA, 2007) an individual has certain basic needs that must be fulfilled before they can begin to work on higher level

Conference and Banqueting Management Assignment

Conference and Banqueting Management - Assignment Example These include federal, education events, entertainment and cultural events. Events are also part of the marketing strategy and business purpose which involves trade exhibitions, fairs and promotions. In short, Event can be defined as the involvement and participation of the group of people to attend corporate goals and objectives A Conference is a formal meeting or forum where people meet and interact for several different reasons. The conferences have been a part of organizations all over the world for many years. Here the discussion is based on some common topic which every member present wants to discuss on. These conferences traditionally took place in the meeting rooms or board rooms of any organization. These conferences are also held in hotels and clubs. Today, with the advancement in technology, conferences have changed into video conferencing over the internet. The purpose of conferences changes with organization to organization and situation to situation. Today, many compan ies are still using the traditional means of conferencing and think that it is better than the video conferencing. This view also differs from company to company, like many organizations think that video conferencing is more effective and helpful for them. ... Conferences have direct relationship with tourism. This shows that the business world and conferences affect the tourism industry up to a great extent. Whenever the peak season of conferences is coming, the rate of tourism due to business also increases as conferencing required travelling of people from one country to another for the purpose of attending the conference. There are many different conference management systems available; many are helping for the traditional way of conferencing while others are helping in the modern way of conferencing like video conferencing. These systems make the conferences more effective and efficient and help in the reduction of many time consuming activities. View on Conference management D Munro’s Views According to the perspective of Mundro, traditional way of conferences was better. He thinks that face to face conferencing sitting together in a place was better than video conferencing. He thought that travelling was leisure and enjoyment for business people and it helped them in getting relieved and enjoying their work life. He thinks that the advancement of technology has affected the conference management and the value of conferencing (Mayer, Pesenhofer, and Rauber, 2006, pp. 359-366). The views of D Mundro are opposing the views of Tony Rogers, as Mundro thinks technology is not helping the conferences of the organizations but it is affecting the conference world (Miguel, 2007 pp. 51-57) Tony Roger’s Views According to the perspective of Tony Roger, new technology has enhanced and made the conference concept much better. As technology has advanced, conferences have changed into

Boko Haram is winning so far in Nigeria Essay

Nigeria has ever faced series of security threatening challenges, but Boko haram is the most powerful sect so far. The sect claims responsibility for several bombings and snip activities in the northern and central Nigeria, thereby placing the nation at the threshold of disintegration this paper describes briefly how the Terrorists use murder, kidnapping, and bombings to pursue a political agenda. Then will introduce the rise of Boko Haram, a radical Islamist sect who is fighting to overthrow the government in Nigeria and create an Islamic state. Many questions in mind like who are this group? Who’s funding it? How they treat their prisoners? The government has been unable to put an end to it, will see at the end if he gets any help from other nations? In past years, most people thought terrorism is only happening in the Middle East countries but now terrorism is every were, even in the most powerful countries. Terrorism is more like terrible and brutal violence with only one purpose of terrified the people. It has two main purposes, to put pressure on the authorities, to spread fear and uncertainty first between the people; their action involves serious violence against a person or serious damage to property, endangers a person’s life. Second, they interfere to disrupt an electronic system, influence the government, advancing a political, religious or ideological cause. According to Rotberg, nation-states fail because they are convulsed by internal violence, and as a result are unable to provide security and positive political goods to their citizens. (2003:1). The Religion Terrorism is one of the most violent they think that dying in a terrorist act is sacred and holy; they see it as divinely commanded. Boko haram is Nigeria’s militant Islamist group which has caused havoc in Africa’s. It seems that the sect may prefer to be called â€Å"Jama’atu Ahlissunnah lidda’ awati wal Jihad† , which can be glossed â€Å"Committed to the Propagation of the Prophet’s Teachings and Jihad† (Mu’azu 2011:17).They believe that anyone who is not governed by what Allah has revealed is among the transgressors. They killed around six hundred people in various attacks in 2011, and the number of casualties doubled in the first four months of 2012 (Pothuraju 2012:1) Because they regards at the Nigerian state as being run by non-believers, even when the country had a Muslim president. Boko Haram members are fully convinced that moral and social decadence has eaten deep into the fabric of the Nigerian society and are resolved to rid the society of corruption and moral bankruptcy by establishing an ideal Islamic society, devoid of political corruption and moral deprivation (Akanji 2009:60) One of the most powerful factors that contribute the Boko haram is that the Islamic Republics, donations from members who links with Al-Qaeda in the Islamic Maghreb, During the interview, on 14 June 2010, Droukdel the leader of AQIM claimed that his â€Å"group would provide Boko Haram with weapons, training, and other support in order to expand its own reach into Sub-Saharan Africa not only to gain ‘strategic depth,’ but also to defend Muslims in Nigeria and stop the advance of a minority of Crusaders† (cited in Pham 2012:3). With funding from government, they are able to buy and train more men than most other terrorist organizations. In effect, with their financial support, Boko Haram backers have become—covertly or overtly—a part of the conspiracy to instigate war against the Nigerian state, civilians, Christians, students, and public institutions (Adesoji 2011:107). Leaders of many Christian organizations in Nigeria have out in support of the government’s decision to declare a state of emergency in the country’s northern states, Borno, Adamawa and Yobe. Many of their peoples live in a terror because of the group targets the religious minority for some of its most brutal attacks. Also, the government in Nigeria has asked its northern neighbor Niger for help in an offensive against Boko Haram insurgents. Plus, the U.S. Secretary of State Hillary Clinton mentioned Boko Haram during her testimony before Congressional committees. She called it part of the same global jihadist movement as al-Qaida and Ansar al-Sharia. Finally, Boko Haram has killed thousands as it seeks to spread conservative Islamic law across Nigeria. Its frequent bombing targets include police, soldiers and Christian churches. Nigeria’s military have been involved in heavy fighting against this sect and hopefully with the help of the other nations, the government gets back the control on Nigeria.

Three Day Diet Reflection - Free Essay Example

Sample details Pages: 2 Words: 685 Downloads: 8 Date added: 2019/02/12 Category Health Essay Level High school Tags: Diet Essay Did you like this example? For my three day diet reflection it was telling me I needed to drink more water, I did not have enough nutrients in my food throughout the day, and I needed to be more physically active. I also need to take more nutrients in my body other than the vitamins I take once day. Healthy eating is not always easy, food is addicting and sometimes we indulge in our cravings. Don’t waste time! Our writers will create an original "Three Day Diet Reflection" essay for you Create order Sometimes we are just so busy throughout our day we do not eat as much nutrients as we need to. Like for me for instance, doing the myfitnesspal app the calories I intake I needed to eat more throughout the day and healthier cause I would eat when I can and sometime its hours within the day. Than thats when I would go to fast food because it was fast and easy, but it also affected my physical health. Also in myfitnesspal app it said I should drink more water and I know I should because I would drink a lot soda before as well. To this day I would exercise and slowly see changes with myself and my body. In the beginning of my diet to lose weight and improve health was one of my main goals, but it can be a bit overwhelming. For the next few weeks my plan is to exercises daily, changing my eating habits, and trying to eat as much nutrients as I can. Most importantly manage my time with everything to stop procrastinating and doing everything last minute. Now I make a checklist for myself and do as much as I can. There are bound to be challenges in your life whenever we start something new, especially when your used to doing a routine everyday. â€Å"You don’t have to be perfect, you don’t have to completely eliminate foods you enjoy, and you don’t have to change everything all at once—that usually only leads to cheating or giving up on your new eating plan† (Segal and Robinson, 2018). To this day I still get cravings, but when I do I either substitute my food with a healthier nourishment, for example when I crave ice cream ill substitute it with yog urt with a lot of fruits on top. Managing my time, changing bad habits, and being physically active you have to stay motivated and positive this will only benefit yourself. Changing your eating habits and working out was a bit difficult at first because it was like a roller coaster for me in the beginning, but as I was doing it constantly it would get easier day by day. I can see the changes in myself about feeling more confident, having more energy, boosting my mood, and most importantly improving my health. There are days when I would eat unhealthy but I also tried to portion my size and exercise the next day. During the week I will regulate my schedule in doing at least 2 miles on the elliptical or treadmill every Monday and Wednesday, for the other days I will try to increase my intensity of my work out and push myself little by little each day. While doing myfitnesspal app it does suggest that I should really intake more in my calories as well with proper nutrients in my food. Especially I should start meal prepping to also avoid myself from going to fast food and I will also be saving money as well. Living a healthy lifestyle can be very stressful because we have times that we are tempted into making the wrong choices. We are human when it comes to failure we learn from our mistakes. Never give up on your goal it will increase your self determination and make you stronger in the future. Personally I still make good and bad choices in life, I still live a life to standards in what I can handle, I push myself to make me better as a whole. We learn from from our failure that challenges us to better, always strive to accomplishing your goal â€Å"you never lose either you win or you learn.†
