Deforestation The Causes Effects And Controlling Techniques Environmental Sciences Essay
Deforestation The Causes Effects And Controlling Techniques Environmental Sciences Essay As we all know that fires, urbanization, and other infrastructures from the main causes of deforestation. Also we All know that living organism in this ecosystem was facing or will suffering from deforestation impact directly or indirectly through other environmental issues that happen because of deforestation. Therefore , in the next few papers we will illustrate to the seriousness and the importance of this problem depending on statistics ,pictures, studies and articles that published on books and internet websites. Introduction Is it right that our planet is under threat of climate changing? It is true that it is related to deforestation? What will happen if we didnt solve this problem? All of these question will be answered in this research. which will give you more information about deforestation, its causes, impacts, some statistics and how we could take people attention to the climatic change and prevent their actions on deforestation to save our planet. The cutting of forests or the destruction of the forests is called deforestation. deforestation term is called in cases that human-induced it or due to the forces of nature as well, so Human are mainly responsible for the destruction. Deforestation for need humans has cut down trees since they first appeared. In modern times the human needs was not limited on food , and shelter, but it surpassed it into weapons ,paper, furniture, paved roads, entertainment places and housing. So, Thousands upon thousands of acres of forest have disappeared worldwide to fill our appetite for wood and land. Deforestation for Profit The governments are often poor and the land is more valuable to large corporations than used for conservation and tourism. for this reason ,in poor countries Governments gives permits and licenses to those who have the money to buy the land and make their money. The activity of Deforestation is a way of making a living, through selling timber , and using the land for growing crops or grazing herds or to provide land for homes and businesses. As you can see in (Figure 1) that companies ,attract and involve the native people who are exist in the forest when they conduct this business. figure : Book: William P. Cunningham, 1990: Environmental Science A GLOBAL CONCERN. Wm. C. Brown Publishers, USA. Raising Consciousness Undoubtedly the reason that makes people more aware than ever of the effects of deforestation as more and more people become affected by climate change and extreme weather events which is the most important consequences resulting from deforestation. All of that would make human think of stopping or reduce deforestation activities for maintaining our atmosphere, slowing global warming , protecting us from floods, and ensuring a reliable and sustainable suppliers of natural resources . Body What is Deforestation? Deforestation is the clearing or removal of trees from an area of woodland or forest for many differing reason usually commercialà [1]à . And it also defined as the destruction of a forest and changing the use of the landà [2]à . Causes of Deforestation There are many different causes for deforestation and they vary widely from location to location. As it is known most of deforestation cases happen by human practices. And this idea is true , but also there are some natural causes leads to deforestation such as : firs, natural disasters(floods). Agriculture and Cattle-Raising The expansion of cattle-raising has also been promoted by the World Bank and the Inter-American Development Bank, as well as through tax incentives and has been closely linked to land concentrationà [3]à . Cattle expansion in the Amazon in the last twelve years has been phenomenal. During this period, the number of cattle more than doubled, from 26million in 1990 to 57 million in 2002. In the process it has gone from representing 17.8% of Brazils total cattle herd to almost one third (see table 1). Table 1:INTERNET: Brazilian Institute of Geography and Statistics (IBGE) www.ibge.gove.be The phrase described how the rapid growth of beef exports from Central America to fast food chains in the United States was driving deforestation.à [4]à Dams and Megaprojects Usually the rivers that extend to thousand hectares or more in the forest have the greatest chance to implement of major infrastructure works , such as building dams for obtaining hydroelectric energy like what happen in Xingu river. It is estimated that nearly all the Amazon forest will be destroyed during the first half of this century if the present trends are increased with the implementation of major infrastructure works in the region.à [5]à Mining In many tropical areas mining is a major cause of deforestation and forest degradation, generating a large number of social and environmental impacts. A recent study published by Third World Network-Africa provides a detailed picture of those minerals in the Wassa West District of Ghana. The main minerals being mined in Ghana are gold, diamonds, bauxite and manganese, but the most dominant mineral commodity is gold.à [6]à Effects of Deforestation Deforestation is a problem with unlimited effects. Environmental problems: Hydrological Studies show that 99% of the water absorbed by the roots moves up to the leaves and evaporates to keep the weather nice and moisture, therefore if trees are cut down it will cause into drier climate. Another important hydrological impact of deforestation is that the soil capacity to store water is affected negatively because after deforestation , litter and other organic residue of plants change soil properties to make it good stores of water. But that water will not stay for long time because it will affected by sun rays which will evaporate most of groundwater. Atmospheric Trees represent a thick cover that prevent the damaging sun rays. And because of deforestation ,the sun rays can deeply penetrate into the forest than before, if that happen trees will wilts and dies . Green house effect: If forest is cut down forest and replaced by vegetation with a smaller biomass per hectare, there is a release of CO2 by burning or decomposition of forest plantà [7]à .Tropical deforestation is a substantial contributor to total CO2 production by human activity ( see table 2.4). TABLE 2 :Edward I. Newman, 2000: Applied Ecology Environmental Management. global climate change: green house gases ,forest fires, and the Pollution that rapidly growing along with population . Soil Drought: Trees absorb water through their roots and release it into the atmosphere. In the Amazon, half of the water is returned in the trees. If the trees are removed, the region becomes drier because it cannot hold as much water. Mudslides and erosions: Roots are existing to prove the soil ,and by deforestation The land becomes unstable because their are no trees. therefore it causes erosion. Economical impacts: In economic terms, forests does not only provide fuel and wood for industry, but they also provide the medicinal plants , fruit trees and nuts, which is the main source of food for forest dwellers. Also The forest have a large economic and environmental benefits , it is a haven for everyone, as they provide them with a feeling of comfort and peace of mind, and give them the fresh air and gains entertainment that any industrial facilities can not provide them , and beautifully landscaped. Therefore, it provides significant economic value through tourism activity. And when governments encourage individuals to cut trees timber and exercising a certain economic activities detrimental to the environment such as set on fire which leads to over-exploitation of forest wealth and the deterioration of its condition. The consequences of these behaviors are: population migration from these areas and the emergence of the problems such as: poverty, diseases, conflict on food, unemployment. Deforestation and biodiversity: Plants diversity No one can deny that we still rely on plants or herbs in the treatment of some diseases, such as cough, constipation and some skin diseases. we will proof this by these two facts about rainforest plants : Rainforests currently provide sources for one-fourth of todays medicines, and 70 percent of the plants found to have anticancer properties are found only in the rainforest.à [8]à Two drugs obtained from a rainforest plant known as the Madagascar periwinkle, now extinct in the wild due to deforestation of the Madagascar rainforest, have increased the chances of survival for children with leukemia from 20 percent to 80 percent.à [9]à (See figure 2)which is Madagascar periwinkle plant. Figure2: Book: William P. Cunningham, 1990: Environmental Science A GLOBAL CONCERN. Wm. C. Brown Publishers, USA. Animal diversity The human species has been the direct or indirect causes of most of the extinctions, especially through habitat destruction. When Europeans first arrived in the Hawaiian islands , there were sixty-eight unique bird species. of these, forty one now are extinct, mainly because of deforestation to create pineapple and sugarcane plantations, resorts, and citiesà [10]à . Fish diversity In this aspect we illustrate that removing forest to build government projects, such as roads and dams, could protect threatened habitat. In the 1960s the Tennessee valley authority (TVA) announced intentions to dam the little Tennessee river for power , flood control, and recreation. opponent fought against this project for years, arguing that the dam was not needed , the cost was too high, the payback was too low, and it destroyed valuable forest , wildlife habitat, native American archeological sites, and recreational, historic, and scenic values. It was revealed that the only known habitat of small paperclip-size fish called the snail darter (percina tanasi) (figure 3) would be destroyed if the river valley was floodedà [11]à .

How to Stop Deforestation We know that , stopping deforestation activity definitely not an easy task, but to reduce the impact of rapid spread of deforestation in previous years and to increase consciousness rate we suggest people to : * Try to use the paper more than once. For example, use both sides of paper. * put the paper in recycling paper box. *Use e-mails to aware your friends about impact of deforestation. *Aware about type of wood and avoid the tropical hardwood, such as ebony and rosewood. And make sure the manufacturer can guarantee that the hardwoods were harvested from agro forestry plantations. Also we Suggest government to: *Create law to deforestation: by making law that cutting trees from forests become a crime punishable by law. *Encouraging companies: that working in reforestation by decrease taxes for them and try to give them all help to increase number of those companies. * using selective timber -cutting instead of clear- cutting: because in selective cutting, foresters remove desirable tree species ,like deformed trees to get rid of them. * posting fire danger warnings and sponsoring television and radio announcementsà [12]à . *reducing demand on wood by: using thinner saw blades in saw mills, which reduce the kerf ,and improved machines that do a better job of processing logos for plywood along with a host of other technologies. special training for workers could also help reduce wood wasteà [13]à . *Farming: is a New methods are being developed to farm more intensively, such as high-yield hybrid crops, greenhouse, autonomous building gardens, and hydroponics. to keep balance between rates of farming and deforestationà [14]à . Conclusion Forests are a source of beauty, food, medicines, also its highly responsible in keeping and sustaining global ecosystems. It is also the home of more than half of all creatures and organisms in this planet. On the other hand we also gain other benefits by deforestation . For example: building the communities, residential houses, factories, and roads ; to be more suitable for the growing numbers of population. By Deforestation we can also convert the forest land to productive land for agricultural uses. As a result, we and all the other creatures on this planet suffer greatly from the consequences of deforestation. So deforestation should be stopped at any cost, especially the illegal cutting of trees. By increasing the government laws and punishment ,and increasing Perception and awareness among people which may leads us to gradual disposal of deforestation. References Books: Edward I.

Annuities Businesses, financial institution, and other organizations invest in annuities to raise money to pay such expenses as bond debts, notes due, or stock dividends. They also invest in annuities to provide for future needs, such as new facilities and equipment or employee retirement benefits. Individuals may purchase annuities, such as an Individual Retirement Account (IRA), or an insurance policy, from insurance companies, financial institutions, or securities brokers. Ã Ã Ã Ã Ã An ordinary annuity is a series of regular payments where each payment is made at the end of the payment period. The payment period is the length of time between payments. Payments are usually made annually, semiannually, quarterly, or monthly. The term of the annuity is the length of time from the beginning of the first payment period to the end of the last payment period. The amount of the annuity is the sum of all payments plus their accumulated interest. Their amount is also called the cash value. Ã Ã Ã Ã Ã The amount of an annuity can be found by using the Amount of an Annuity table. The table lists the value of an annuity of $1 compounded at various rates for various time periods. To find the amount of an ordinary annuity using the annuity table, multiply the payment by the appropriate table value. The interest earned can be found by subtracting the sum of the payments from the amount of the annuity. For example: Brian purchased an ordinary an...

Is The Berlin Wall A German National Symbol - Free Essay Example
Sample details Pages: 2 Words: 470 Downloads: 1 Date added: 2019/05/07 Category History Essay Level High school Tags: Berlin Wall Essay Did you like this example? The Berlin Wall was a physical symbol of the difference between the West and East Berliner. This physical border became a border of culture that divided social contexts and expressive forms. Communities along borders in all different places and countries are constantly defined and redefined by the changes in borders, finding an identity is difficult for people who live in these areas. Donââ¬â¢t waste time! Our writers will create an original "Is The Berlin Wall A German National Symbol?" essay for you Create order How did the wall change the traditions for these two separate Berlins? How did this wall affect the sense of home for the East and West Berliners? How did this wall change and affect these peoples identity? I have found interviews and accounts from Berliners who remember the building of the wall, Berliners who lived close to the wall, Berliners who grew up during this time and especially remember a divided Berlin and some refugees who had escaped to the West Berlin side from East Berlin. Before beginning with the separation and difference in these two Berlins, we must look at Germany as a whole. Starting with what Mary Beth Stein, (PhD) calls the German problem. The German national identity has been said to show feelings of inferiority, in which was seen to cause extreme nationalistic motives which ultimately brought about the creation of the German Reich, the need to show the world that the German nationality was of value. Germany was in a tough position after 1945, not only because of the events leading up to the wall, but mostly because of the extreme German nationalism which caused World War Two that ended up being extreme misfortune for Germany, and now they could not control their own political fate because of the defeat and surrender after the war. Now, not only could the entirety of Germany find an identity, but they were being split into two separate identities, both competing for legitimacy while trying to represent and signify their nation. One issue that was faced by these two new German states was a historical and political aspect. What were the select aspects of German national identity that could be carried on throughout the years but was still far enough from the most recent German experience? After 1945, two Germanies were continuing forward with different aspects of the German past, while both still wanting to maintain legitimacy. This was extremely difficult in the years from 1945-1949, when Germany was going through a denazification cleanse formulated by the Allies in the Allied occupation zones. Many German national symbols were eradicated like the national anthem and the flag which can be a symbol of identity and sovereignty. Later, both German states brought back the original black, red and gold flag which was associated with the liberal-democratic tradition and the revolution of 1848. The GDR (German Democratic Republic) eventually adds the emblem of a hammer and compass that is circled by a wreath in 1959.
