Introduction
When most people think of deforestation they think of the rainforest. However, this is an environmental issue that takes place all over the world. In the following pages I will expand on what exactly deforestation means, and why as a world we have a need for it, even though it has adverse effects globally. Deforestation affects our environment by reducing biodiversity, changing the water cycle, affecting soil erosion and also plays a part in the ongoing phenomenon of global warming. Since, this is a global matter, the United Nations has implemented policies to help reduce the damage done by deforestation. The UNREED policy is globally based, while the REED+ policy is nationally based. I will also explain the importance of these policies and what they mean.
Understanding Deforestation
Deforestation is simply the killing of trees and conditions being where trees can no longer survive where they once stood. It can occur through natural changes in climate and man’s need for cleared land. For instance, if weather conditions occur that make a forested area to cold, dry or wet, killing all the trees, and making it to where they can no longer survive the area, this is natural occurring deforestation. This type of deforestation has occurred in the past. During the Pleistocene period, which occurred 1.5 million to 10,000 year ago, glaciers melted. This melting caused sea level to rise, and wiped out forest from areas of Europe, Asia, North America and other flooded areas. Over the last 1,000 to 100 years there have been varying cooling and warming trends around the globe. The cooling trend have caused forest at high altitudes to die, due to the extreme cold conditions. The warming trends have caused an increase in the about o...

Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .
Deforestation: an act of pure terrorism towards the forests of the Earth, the most evil and brutal punishment to wildlife imaginable. Every year, thousands of trees in multiple forests are chopped down either for the wood humans can make resources for or to make room for more humans to grow as they continue to rise in population. Many problems can result from deforestation: loss of habitat to animals that rely on the forest trees to survive, resulting in endangerment or extinction as the animals must forcefully move to another place to thrive in numbers while avoiding the invading humans, and the effects of potential global warming can occur due to the carbon dioxide released by the machinery used to bulldoze the trees down, and only a few
Deforestation is a widely used term, but one with different meanings. Disturbance deforestation refers to all man made disturbances that alter a forest, these are the most common. This argumentative essay discusses the positive and negative aspects of deforestation. In the first part of the essay the pro arguments of deforestation will be discussed. For example, the issue of Global population and how forests are being used, land use and the ways forests contribute, wood use, forest growth, destruction and the reasons for cutting down the trees. The second half of the essay will cover the issues that are harmful to the environment because of deforestation. Many environmental issues take place everyday; a big question that arises, is if the global economy will ever finds middle on the issue of forest thinning. If deforestation was used only in the most crucial of times, the world might become a better place.
General Information: First off, deforestation is the clearing of forests or areas with trees to be converted into something else after. There are a few different ways forests are cleared. Clear cutting is simply removing everything in sight. Patch cutting is the removal of trees in specified patches. Strip cutting is removing trees in selected strips. The most environmentally friendly method is known as selective cutting. This is the removal of only selected trees, leaving the others un-harmed. The technique used most during deforestation is the slash and burn technique. This uses the basic cutting method of clear cutting, but afterwards everything that remains is burned to ash.
Deforestation began with man’s ability to manipulate his environment. Wood has always been a primary source for shelter and has been affected by human expansion. As the worlds population grew, so to did the need for wood to make housing. As cities grew so did the demand for space to accommodate the growing population. Throughout history and even today, man has manipulated the environment affecting it’s resources.
“The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests
Though deforestation has increased at an alarming rate throughout the past fifty years, deforestation has been performed during the course of history. According to the World Resources Institute, a majority of the world’s enduring naturally occurring forests are found in Alaska, Canada, Russia and the Northwestern Amazon. Research has demonstrated forests are more likely to be destroyed and repurposed where economic revenues tied to agriculture and pasture are prominent, typically attributed to advantageous weather conditions, or lower expenses of demolishing the forest and delivering merchandises to the global
Deforestation, defined by biologist Charles Southwick as "the destruction of forests; may involve clear-cutting or selective logging" (p. 365), is a predominantly human-driven process that is dramatically altering ecosystems worldwide. "Clear-cutting" involves the indiscriminant removal of every single plant and tree species from within a selected area. The other major process of deforestation, "selective logging," focuses removal efforts on only specific, predetermined tree species within a chosen area. The statistics gathered about human deforestation over time are considerable, and they can be somewhat controversial. Depending on the source and the location selected, the magnitude of deforestation varies. Southwick estimates that, approximately 10,000 years ago, 6.2 billion hectares (23.9 million square miles) of forest existed on earth (p. 117). That figure is equivalent to 45.5% of the earth's total land. He further estimates that, by 1990, this amount had declined 30%, with only 4.3 billion hectares of forest remaining (p. 117). Southwick also acknowledges other estimates that place the total amount of deforestation between 50% and 75% (p. 117). NASA has similar deforestation statistics that confirm these trends. According to their website, 16.5% of the Brazilian Amazon forests have been destroyed. They also note similar magnitudes of deforestation in Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), despite the significantly smaller total area of forest within these countries. These grim figures are somewhat tempered by the NASA finding that, over the past ten years, the deforestation rate has declined from 6,200 square miles per year to 4,800 square miles per year. Though this trend is n...
Deforestation is the amputation of trees from forest areas more swiftly than they can be replanted or regenerate naturally. The fact that trees play an incredibly momentous part in stabilising climate, atmospheric composition and soil structure, removing trees rapidly becomes a major problem. There are numerous reasons behind the felling of trees by mankind. The Amazon basin is a prime example of humans exploiting rainforests. Within this tropical rainforest lie a vast variety of tree species, with many uses, giving humans even more reason to exploit this area.
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation.
Deforestation is the elimination of existing trees from the earth; attributable factors include urbanization, logging, ranching, and farming and to some extent land speculation. Land speculation can be included as cleared land is more valuable than forested land. Deforestation, done in the name of progress, and the long-term, devastating effects of it, is killing our planet.

Scientists themselves are just beginning to understand the serious problems caused by deforestation. Deforestation occurs all over the world by all types of people. Peasant farmers even add to the problem because in most tropical countries the farmers are very poor only making between eight hundred and fifty four hundred dollars annually (NASA Facts). Therefore, they do not have enough money to buy what they need to live therefore they must farm to raise crops for food and to sell. In these poor countries the majority of people are peasant farmers this farming adds up to a great deal of deforestation. These farmers chop down a small area of trees for there plot to farm on and burn the tree trunks (NASA Facts). The combined number of farmers maintaining this process creates a great deal of clearing and burning of the land they need to cultivate, which results in land being treeless. Commercial logging is also another common form of deforestation. This commercial logging wipes out massive amounts of land sometimes deforesting several miles at...
