Softwoods from areas under boreal forest are used in the paper and construction industries, while tropical hardwoods are used in the manufacture of furniture and for construction purposes. In South American countries, forest and woodland areas are also heavily exploited for wood-fuel, which is the main source of energy. Following Ehrhardt-Martinez (1998):
"Deforestation in developed countries has reached very low levels, it accounts for the loss of 16.3 million hectares of forest per year in developing countries -- an area approximately twice the size of Portugal. An estimated 15.4 million hectares of forest loss occurs each year in tropical regions, with the worst losses occurring in Latin America and the Caribbean (7.4 million ha) (568)
Clearly, the exploitative decline in forest and woodland resources is not sustainable in the long term and a number of environmental problems, including soil erosion and biodiversity losses, have developed as a result. Improved road access into deforested areas is likely to encourage population influx and increased shifting cultivation (Margulis 39).
Farmers are then encouraged to trans...
These strategies are very successful helping to establish a special culture of forest management and land use (Ehrhardt-Martinez, 569). For the highlands, this meant more emphasis on cattle-ranching, generating meat and dairy products for the growing urban markets, and less importance for traditional subsistence crops like corn, wheat and barley. The establishment of all-weather routes meant that areas which had only been accessible during the dry season could now be used for continuous product extraction, promoting permanent settlement which in turn also increased the demand for local food products. it should be noted that forests, while not the only, are still the main source of 'reserve land areas' to be gradually included in the pool of cultivated areas (WRM 1998). Due to the low commercial scale of remaining valuable timber species, it is usually not worthwhile to open a new road in a mountainous region just for the sake of timber extraction; this thus eliminates any prospective 'indirect' impact. The extraction of logs here may rather be a by-product of forest-clearing implemented for general purposes of colonization (Margulis 89). According to road distance and market requirements, either all types of firewood are cut and used across the board for conversion, or hard species with a high energy content are selected. In the case of across-the-board utilization, charcoal-burning would indeed be a candidate as a cause of deforestation, provided that the once-and-for-all rent from clearing and charcoal conversion is in fact the decisive motivation within the landowner's resource-use strategy.

Eilperin (2009) mentioned that the earth’s surface temperature has been increased around 0.750 C during the last century itself and the atmospheric temperature may even go up by 6 degrees before the end of the current century (Eilperin). Global warming and climate changes are some of the worst problems facing by the human community at present. Atmospheric temperature is rising rapidly for the last few decades and as a result of that unexpected weather calamities are occurring. Many studies have proved...

Amazon Deforestation

...?Amazon Deforestation Introduction Global warming is one of the major concerns of the world today. The problem is caused by the increased greenhouse emissions coming from different countries worldwide.

Therefore, preservation of forests is one of the surest ways of slowing down global warming. This begins by preserving Brazil’s Amazon rainforest, which is at threat of disappearance due to deforestation. Brazil’s Amazon rainforest is one f the world’s largest tropical rainforest.

Rainforest deforestation

...Rainforest Deforestation Introduction Rainforests are regarded as earth’s most intricate ecosystem. Rainforests, or widely known as jungles, have been the leading type of flora in tropical regions for factually millions of years, and underneath their towering shades exist a diversity of life forms which is unequaled anywhere else (Bosetti & Lubowski 2010). But sadly, these rainforests are struggling. These intricate and abundant ecosystems, which have endured thousands of environmental changes, are currently confronting the threat of extinction. Human activities, rather than natural forces, are creating more damage on the rainforests, such as deforestation. Rainforests are home to the most important...

Effects of Deforestation

...Effects of Deforestation Deforestation encompasses annihilating expansive forests’ tracts through cutting or burning mainly by human with the intention of establishing varied activities, for instance, farming. In most cases, this is permanent forests’ destruction to allow the commencement of varied activities whose duration is quite long to the extent humans do not consider replanting to replace lost vegetative cover (Spilsbury 26). Generally, this annihilation of vegetation poses extremely negative effects on the environment as well as climate. It changes the landscape dramatically in a short period. The changes in landscape range from the local loss of biodiversity, to large-scale effects on the...

Deforestation Crisis

...Question One of the major environmental concerns in the world is tropical deforestation. Over the last decade, almost 13 million hectares of forest land has lost due to factors like over population, construction and agricultural expansion. Forests play an important role in the sustenance of life on earth; they attract rain and most importantly balance carbon dioxide in the atmosphere. Therefore, deforestation is a serious matter that has raised concerns in the entire world (Spilsbury 44). United State of America is one of the core countries characterized by high urban and industrial centers. It is also capital intensive, have high production technology patterns, high wages and low exploitation of labor....

Deforestation and Marginal Cost

...World has been at the alarming condition of land deforestation. Deforestation is done either by clearing the entire land or degrading it. Main reasons cited for the purpose are cultivation, agriculture, collection of fuel wood, logging, mining, industrial development, large dams and tourism etc. All businesses conducting these activities provide reasons that apparently justify and for the short run only. For instance, commercial companies conduct logging for their need of timber and defend themselves with responses that logging is conducted with selective process and the entire forest is not cleaned up which ensure that forest re-grows. However, here the marginal cost incurred is much higher than...
