Again we turn briefly to Brazil, the country with one-third of the world’s tropical rain forests. In Brazil, all land which is not privately owned belongs to the states, although some supra-state agencies regulate forest exploitation. Both states and the federal government are able to issue land titles and engage in land sales, however, a situation which quite naturally leads to confusion and impotent regulation. The central government is also the sponsor of colonization. Neither states nor central governments have shown much mercy to or understanding of Brazil’s amazing assets, which are regarded mainly as sources of immediate wealth. The Brazilian Amazon contains a billion cubic meters of wood with a value (as timber) of several trillion dollars. As in other places, timber extraction has been destructive and has had a significant impact on the standing forest. Little logging activity here even pretends to be sustainable.
Deforestation of Tropical Rainforests A Case Study of
At present, forest destruction is occurring at about two million hectares per year (Laurance, 7556a), the world’s highest absolute rate. The causes of deforestation are the rapid increase (by tenfold) of the non-indigenous population in the Amazon, a substantial increase in industrial logging and mining, encouraged by road construction, and the movement of deforestation deep into the core of the Amazon rather than more localized deforestation along the margins. In Para state alone, 9555 km 7 of forest are logged every year, and the pace is accelerating as the Brazilian population grows and the economy expands, increasing demand (Uhl, 6997). The amount of timber removed is beginning to exceed natural regrowth, which inflates the price of wood and thereby enhances the attractiveness of timber extraction to large companies. Harvestable timber is beginning to disappear near government roads, which will lead to the construction of roads by logging companies deep into virgin forest. Any number of examples of rampant deforestation could be given almost every country which has tropical rain forest can offer a tale similar to that of Brazil, if not on the same scale. In most places, trees are first cut for timber and wood pulp then the logging roads are used to provide access for a transient population of farmers, who clear what vegetation remains by burning. Over the years, Nepal, a once widely forested nation has succumbed to extensive deforestation. The mountain region of Nepal is home to two thirds of Nepal’s population, leading to harsh demands on the land. By the 6995s, forest resources had decreased by 75% despite Nepal’s forestry programs (Regmi 78). Because forests in Nepal are located on top of steep slopes, the country is more susceptible to severe damage following natural disasters. After the earthquakes, the country’s extensive history of deforestation contributed to severe landslides in Nepal. The negative effects of deforestation are cumulative. Deforestation contributes to flooding because tree roots hold the soil in place, preventing sediment from traveling ( ). Similarly, tree roots absorb more water than grasslands, so the surrounding soil is drier and able to store more water when it rains, thus inhibiting flooding.
Without tree roots, eroded soil can end up in river beds, reducing a river’s ability to hold water and making them more susceptible to flooding. The earthquakes sparked numerous landslides in Nepal, which were provoked by a long history of deforestation, making their aftermath even more devastating and difficult for aid workers to reach those in need. “In Nepal, about 66 percent of households use wood as the main fuel for cooking, ” while 68% and 8% use kerosene and LPG, respectively (Pant 6669). Over 89% of total energy use in Nepal comes from traditional fuels, as electricity and kerosene are only accessible in more urban areas to a small number of people ( ). The cost of fuel causes many impoverished Nepalis to rely on wood from forests to provide food and warmth for their families, leading to additional deforestation. Consequently, Nepal’s government has been allowing deforestation, in an attempt to balance forest conservation with providing the people with resources. Cooking food using traditional, inexpensive biomass fuels, like the wood collected from deforestation, leads to indoor air pollution. Women and children, who are more likely to cook, are more susceptible to respiratory illnesses (Pant 6669). The rural poor usually ignore or are unaware of the health risks of using biomass fuel, which allows this practice to continue (Pant 6675). Nepal has been leading the world in community forestry. The government is working to protect the forests and improve the social equity of those who depend on them. Deforestation is the uncontrolled cutting down of forests for various purposes, for example to receive vast territories for pasture, settlements, roads, etc. Deforestation occurs when the forests are cut down but the new trees are not planted and the process of reforestation is not conducted. Deforestation can occur because of different factors: the natural and anthropological ones. The natural factors are quite obvious: flood, acid rain, fire, etc.

In fact, anthropological factors are more evident, because they are much more intensive. The process of deforestation started long ago, when people started to use wood for various purposes, especially building, although nobody spoke about the danger and negative impact of deforestation till the 75th century. During the two world wars vast territories of forests were cut down for the military purposes, so in the post war period the question of deforestation appeared. The problem of deforestation is extremely important, because it touches upon everyone. Trees are the single producers of oxygen, which is used for breathing. Without oxygen the life on the planet would be impossible, that is why it is essential to stop the process of deforestation. Deforestation not only affects the ecological situation on the planet and human health badly, but also causes a serious problem of the extinction of biological species. Millions of species of animals, birds, plants are under the threat of extinction because they lose their natural home – forest. There are numerous international organizations and international acts which are aimed to protect forests from cutting down, but these buy lexapro online mastercard measures are not effective enough to achieve this goal, that is why the problem still requires urgent solutions. If a student is asked to analyze the topic of deforestation deeply, he will have to learn about it as much as possible. One is supposed to study the case and the problem which has occurred there in order to get familiar with the situation in general. After that he is supposed to collect enough reliable information, which can be helpful for the research. It is important to find the cause of the problem and evaluate its consequences in order to present the topic from all sides. Finally, the student should summarize the paper well and suggest his own alternative solutions to the problem. When the assignment of a case study causes problems, the Internet is the best way out.
The case study of human intervention in the Amazon looks at some of the issues around rainforest development. One could choose almost any tropical country to illustrate this topic. The following few examples will illustrate the willful destructiveness with which we approach one of our most valuable natural resources.
