Forests Extinction Essay, Research Paper


Can you picture our earth without forests? Many of us can?t. Forests cover


approximately one fifth of the worlds land surface and play an important role in


our everyday lives (Dudley 4). Forests provide us with many products and


services from helping maintain erosion to providing jobs for our citizens.


Humanity depends on the survival of a healthy ecosystem and deforestation is


causing many social, economic and ecological problems. One ecological problem is


Global warming witch is caused when carbon is released into the air after the


burning of forests. Governments and industries must become more aware of these


consequences of their activities and change accordingly. They need to cooperate


with forest management and work towards a future that benefits all. Humans need


to be educated about the current issues of the forests in order for us to save,


preserve or sustain these places that provide us with so much. Humans depend


tremendously on the world?s forests, but yet were the ones destroying them.


For humans, the forests have many aesthetic, recreational, economic, and


cultural values. Timber and other products of the forests are important


economically both locally and as exports. They provide employment for those who


harvest the wood or for those who make products from the living forest. Forests


also provide us with medical drugs, dyes and fabrics. There are many people who


are dependent on forestland for their livelihoods. One third of the world?s


people depend on wood for fuel as a significant energy source (Dudley). Not only


do the forests provide some people with homes, but also provides a popular


setting for ecotourism, which includes hiking, camping, bird watching and other


outdoor adventure or nature study activities. All these activities and products


the forests provide us are at great risk from deforestation. Not only do forests


provide us with all this but also protect soil from erosion and reduces the


risks of landslides and avalanches. Trees help sustain freshwater supplies


therefore are an important factor in the availability of one of life?s basic


needs. Forests affect the climate and are also a very important source of


oxygen. One major factor that the forests carry is that they are the home to


over one half of the world?s total species (Dudley). Currently we are


discovering 20 new species of insects and 15 species of plants each day (Dudley


13). ?Recent reports by the World Resources Institute have shown that more


than 80% of the plant?s natural forests have already been destroyed?


(Hatch). Yes humankind is the cause of deforestation, however us humans are also


capable of having a positive effect on this crisis. Tropical forests cover about


10 per cent of the world?s dry land surface, mostly located in South America


and Asia (Dudley 6). In the tropical forests of the world, deforestation is


occurring for agriculture and livestock pastures. The main cause is the unequal


distribution of land (Anderson). Temperate forests are found in land areas that


are warm enough and low enough to support trees but not so hot to be tropical.


They are found in North America, Europe and cooler parts of Australia (Dudley


4). The problems in temperate forests are not so much the decrease in overall


forest area, but the substantial change in the types of forests and their


ecological diversity and stability. Commercial forestry is the main cause of


deforestation in temperate forests. ?In very broad terms, the total area of


forest in Europe, the USSR and North America is likely to decrease only slightly


in the medium future, but the proportion of forest existing as plantation is


liable to rise sharply? (Dudley 66). This however is going to lead to an


increase in conflict between the recreational and conservation interests and


will also tend to make forestry a more capital-intensive operation, thus


providing fewer jobs. Since so many people are dependent on the world?s


forests, deforestation will have a social, economical and ecological effect on


the world. Most of these effects are negative ones. The loss of forestlands is


connected to desertification, which translates into there being fewer trees,


thus decreasing the future forest workers employment. Heavy rainfall and high


sunlight quickly damage the topsoil in tropical rainforest, causing them to


regenerate slower and also providing insufficient farming grounds. When forests


are replanted there will also be a loss in quality. Also the medical treatments,


cures and vaccines will never be discovered if there are no forests to discover


them in. There may be a loss of future markets for ecotourism. The value of a


forest is often higher when it is left standing than it could be worth when it


is harvested (Dudley). Deforestation can cause the climate to change which could


cause and increase in floods and droughts. Global warming is a big factor in the


destruction of trees. Forests store large amounts of carbon that are released


when trees are cut or burned. It is said that deforestation and the burning of


biomass will be responsible for fifteen percent of the greenhouse effect between


1990 and 2025 (FAO). Because of global warming ranges of tree species could


shift with respect to altitude and latitude (Humankind 2). Furthermore, the


stress of such environmental change may make some species more susceptible to


the effects if insects, pollution, disease and fire (FAO). Also, areas of trees


may be lost and genetic diversity may decrease. The clearing of forestland


results in

increase of erosion and landslides. Landslide is a descent of a mass


of earth and rock down a mountain slope. Landslides may occur when water from


rain and melting snow sinks through the earth on top of a slope, seeps through


cracks and pore spaces in underlying sandstone, and encounters a layer of


slippery material, such as shale or clay, inclined toward the valley (Encarta).


Logging has directly and indirectly damaged spawning grounds, blocked river


channels, raised water temperatures and caused water levels in streams to


fluctuate dangerously. Therefore, the removal of tress can reduce the viability


of fist stocks in their watershed and down streams environments. People destroy


or degrade forests because, for them, the benefits seem to outweigh the costs.


Underlying causes include such issues as poverty, unequal land ownership,


women?s status, education and population. Immediate causes are often concerned


with a search for land and resources, including both commercial timber and fuel


wood (Dudley). The government and industry play a huge role in the destruction


or stability of forests. The government is the major aspect in controlling and


maintaining the forests. They have a huge say on what can and can?t be done.


For example on March 14th 1996 the senate voted 54-42 against repealing a


section of the 1995 rescissions law that allows the forest industry to salvage


burned and downed trees from national forests (Shuster 1). They can restrict


loggers by making laws but also are the link between compromising with the


environmentalists. High unemployment and job loss is usually blamed on the


restrictions set on foresters. However this is a myth. Most of this unemployment


is from worldwide economic change. The production of value-added forest products


would create more jobs and bring more wealth to these logging communities. The


whole goal of this would be to reduce the pressure on the forests. If commercial


forestry is to have a future, its methods need to become more ecologically sound


and sustainable. The technique of salvage logging, removing dead and diseased


trees from the forest, is good if the loggers don?t take advantage of it and


know what trees to go after. Another affective method logger?s use is known as


whole tree harvesting. This uses all of the wood from a tree. The branches and


the treetops are converted into wood chips. Whole tree logging provides more


jobs for the people and more products to be sold for the economy. The government


must play a greater role in forest management to protect the environment and


employment. The government should ensure that the interests of all stakeholders


and as well as the long-term effects associated with forest areas are taken into


account during forest planning. Governments should stop defending the forest


industry from criticism and end the practice of subsidization. Propaganda


originating from governments and corporations requires elimination if the public


is to be able to make the right choices. Probably only the action of concerned


citizens and consumers will compel government and industry to make changes in


the forests. Individuals can communicate their uncertainty about the future of


the world?s forests to politicians, corporate executives and non-governmental


organizations through personal communication in the form of letters, telephone


calls, faxes and e-mails. Deforestation is a serious problem, but humans can


make a difference. And individual as well as a business can practice green


consumerism. They can make an effort to purchase the most ecologically sensitive


products. Recycled paper is always available, which can reduce the demand for


timber. One of the most important ways a person to have a positive effect is to


reduce his or her consumption of forest and related products. An increase in the


participation of reducing, reusing and recycling is necessary. Education is one


of the most effective ways to promote change in our environment. Society should


educate people of today to change their ways and teach the younger generations


to have respect for nature. The young people in our society should also be


taught about the biological, social and economic values of forests.


Environmental conservation should be as important as math, physics, and history


in school. Workers should be taught to use technology to enhance forest


ecosystems instead of destroying them for reforestation. If humans would just


see themselves as a part of nature, they will respect it so much more and not


just exploit it for its resources. Humans bear the responsibility for


deforestation and the global ecological crisis. But humankind has the abilities


and potential to change its ways and prevent the destruction of our world?s


forests. If the forests are protected and regenerated they will benefit us all


in many ways. Trees will help benefit the land from erosion. Endangered species


will have better chances for survival. Human health will benefit from medicinal


compounds that are given a chance to be disvocered. Local economies will benefit


from ecotourism and consumers worldwide will gain satisfaction from knowing that


their wood products were harvested in a sustainable manner that left four out of


five trees standing (Greenpeace). In order for this to occur humans are going to


have to undergo some degree of ideological change. Humans are going to have to


live more sustainable lives and become closer with nature. Once the crisis of


deforestation has passed, humankind will enjoy a finer existence, and will look


forward to a bright future.
