Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.[1] Examples of deforestation include conversion of forestland to farms, ranches, or urban use.
More than half of the animal and plant species in the world live in tropical forests.[2] Contents * 1 Causes * 2 Environmental problems * 3 Economic impact * 4 Forest transition theory * 5 Historical causes * 6 Industrial era * 7 Control * 8 Military context * 9 See also * 10 References * 11 External links |
The term deforestation is often misused to describe any activity where all trees in an area are removed.[not in citation given][neutrality is disputed] However in temperate climates, the removal of all trees in an area[not in citation given]—in conformance with sustainable forestry practices—is correctly described as regeneration harvest.[3] In temperate mesic climates, natural regeneration of forest stands often will not occur in the absence of disturbance, whether natural or anthropogenic.[4] Furthermore, biodiversity after regeneration harvest often mimics that found after natural disturbance, including biodiversity loss after naturally occurring rainforest destruction.[5][6]
Deforestation occurs for many reasons: trees are cut down to be used or sold as fuel (sometimes in the form of charcoal) or timber, while cleared land is used as pasture for livestock, plantations of commodities and settlements. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also been used in war to deprive an enemy of cover

    I just wanted to follow up on our conversation in regards to Roy Walluk’s evaluation. Luci Fink in payroll, received separation documents for Mr. Walluk. Since he is at a Pay Increment step, Luci contacted Corey to verify if we had received an evaluation so they can process the final pay at the correct pay rate. When I received the message from Corey, Luci had already contacted the Foreman, Joseph Johnson, to ask for the evaluation. Mr. Johnson had stated he didn’t have an evaluation ready for Mr. Walluk. Luci informed him that she would process the separation as she only has a couple of days to process the final pay for a separated employee, per the contract, and she couldn’t wait until the evaluation gets finalized. Luci…

    The truth of this though is that we as humans are trying to industrialize and develop the Amazon more and more every day for our own purposes. We are deforesting the forest; also known as deforestation. Since 1980 more than 580,000 square kilometers (224,000 square miles) of the Amazon forest has been destroyed due to deforestation.

    A tropical rainforest is an ecosystem that occurs roughly within 28 degrees north or south of the equator (equatorial zone between the Tropic of Cancer and Tropic of Capricorn). They are characterised by their humidity (average of 88% in the rainy season and 77% in the dry season), hot temperature (average 27.9 °C during the dry season and 25.8 °C during the rainy season) but more importantly their extremely high rainfall (torrential rainfall - between 1,500 mm and 3,000 mm annually). Tropical rainforests contain the most diverse range and highest volume of plant and animal life found anywhere on the Earth, however, they are amongst the most threatened ecosystem globally due to the large scale fragmentation due to human activity and expansion – 16% of the Earth’s surface was once covered by tropical rainforest, yet the figure has significantly dropped to approximately 6% with no optimism of it increasing again. In this essay I will focus on the Amazon Rainforest, it is 2 times the size of India harbouring 10% of the world’s known species and is home to 350 ethnic groups.…

    This chapter was very informative and gave a lot of information about the reasons of deforestation. I knew that logging and agriculture were major causes of deforestation, but this chapter taught me that mining too is also a big factor. The author was very knowledgeable about this subject and wrote in a way that was very easy to understand. This chapter also gave a very thorough explanation of the impacts of deforestation on the lands. Through this chapter, the author explains how just because a few trees are cut down, the water supply diminishes and can lead to drought as well as many other issues that I did not know about. This is probably my favourite source about this deforestation problem as it was easy to understand and the author did not drag out his writing and got to the point very quickly. It was a good read!…

    The main idea of the article is the affect of deforestation on the environment, wildlife and climate change. Deforestation results in soil deterioration. Forests store nutrients that are required for all plant life. Without trees to fill these roles, many forest’s lands can quickly become barren deserts. Deforestation also impacts the habitat for million species. Majority of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover they quickly dry out. Trees also help conserve the water cycle by returning water vapor back into the atmosphere. Trees remove carbon dioxide from the atmosphere through photosynthesis. Cutting down forests will cause a decline in photosynthetic activity which results in the…

    The Amazon Rainforest, located in the northern part of South America, is the largest rainforest on Earth, containing more than 60% of Earth’s fresh water, over 20% of oxygen on Earth, and huge amounts of carbon dioxide (ACEER). However, the Amazon Rainforest has been deforested principally in order to provide land for the locals who were homeless due to poverty, overpopulation, and government policies. Also, economic reasons such as providing land for cattle ranches, agriculture, logging, and mining (Maczulak) increased the rate of deforestation. In fact, since 1988, over 141,470 square miles of the Amazon Rainforest have been deforested (INPE). The imprudent use of the resources and land of the Amazon Rainforest is destroying the…

    The Amazon rainforest is the largest tropical rainforest in the world which covers over five and half a million square kilometers. Over half of the Amazon is located in Brazil but also in South American countries; Peru, Venezuela, Ecuador, Colombia, Guyana, Bolivia and Suriname. (Science Kids, 2013). During the past 40 years, 20% of the Amazon rainforest has been cut down, this percentage could be higher but was not put in account due to logging.this causes damage and shows that there is less seen cuts. Scientists says that 20% trees could be lost in the next two decades. (National Geographic, 1996) The Amazon gets worse and worse every time it is observed. The main cause for this is deforestation. This investigation will show what is happening to the Amazon Region and what could be the management for it.…
