What is deforestation?
Deforestation is when humans remove or clear large areas of forest lands and related ecosystems for non-forest use, where the trees are never re-planted. These also include clearing for farming, ranch and urban uses. This results in damage to the quality of the land. Forests still cover about 30 percent of the world's land area, but groups of forest the size of Panama are lost each and every year.
How deforestation works
There are many different methods of deforestation for many different purposes, all of which end with the same effect. These include land clearing to prepare for livestock grazing or expansion of crop planting, commercial logging and timber harvests and slash-and-burn forest cutting for subsistence farming. There are also many natural events that result in deforestation, such as volcanic eruption, stand wind throw from hurricanes, catastrophic forest fires, or changes in local climate and rainfall regimes, which only represent a small fraction of deforestation worldwide.
Who deforestation effects
The act of deforestation results in many different effects, both positive and negative. Positive effects include job increases in farming as there is more land to develop crops, ect. It increases the economic value to land owners and creates land free to use for building. It also gives poorer people living nearby the affected area jobs, food and space. However some negative examples include soil erosion, where soil and in them are exposed to the sun’s heat. Soil moisture is dried up, nutrients evaporate and bacteria that help break down organic matter are affected. Eventually, rain washes down the soil surfaces and erosion takes place. Soils never get their full potential back. Another includes climate change. Plants absorb Carbon Dioxide CO2 which is a greenhouse gas from the atmosphere and uses it to produce carbohydrates, fats, and proteins that make up trees. In return, it gives off Oxygen. Destroying the forests mean CO2 will remain in the atmosphere and in addition, destroyed vegetation will give off more CO2 stored in them as they break down. This will alter the climate of that region. Cool climates may get a lot hotter and hot places may get a lot cooler. Loss of biodiversity is also an example, where many wonderful species of plants and animals have been lost, and many others remain endangered. More than 80% of the world's species remain in the Tropical Rainforest. It is estimated that about 50 to 100 species of animals are being lost each day as a result of destruction of their habitats, and that is a tragedy. These facts go to show that deforestation affects us humans and our wildlife both positively and negatively. However the negative facts outweigh the positive. How can farmers farm if the very soil they are using is eroding? What if cool places such as Antarctica get a lot hotter and the ice begins to melt? will it raise water levels and flood countries we once knew, as a result of our actions? Will beautiful wildlife we saw as children only be seen in history books because they lost their homes?
Why deforestation is positive
There are quite a few reasons for why deforestation is positive. These can include increasing economic value to land owners and create land free to use for buildings. This makes it possible for communities to be built as forests make way for residential houses, office buildings and factories. Deforestation can also mean the conversion of forest land to productive land for uses like farming. This results in better and more abundant production of food and materials. Economically, deforestation can contribute in giving many communities the opportunity to make positive changes in their lives, such as poor Brazilians working in the Amazon, where they get jobs, food and space.
Why deforestation is negative
Unfortunately, the negative effects outweigh the positive when it comes to deforestation. Some of which include exposing soil to heat and rain.
and Agriculture Organization (FAO) of the United Nations has estimated that the annual rates of deforestation in developing countries were at 15.5 million hectares for the period 1980-1990 and 13.7 million hectares for 1990-1995. The total forest area lost during the 15year period was approximately 200 million hectares. The tragedy lies in the fact that most of these deforested lands are not suited for long-term farming or grazing and they quickly degrade once the forest has been cut and burnt. In fact…
Poffenroth UNVS 96 GB Junior Year December 1, 2014 The impact on Tropical Rainforest Deforestation What is Rainforest Deforestation? The term raiforest deforestation can be described as all trees are removed or harvested by humans in an area. Originally, the earth was covered by approximately 14.8 billion acres of forest by 8,000 years ago (Rainforest Alliance 1999). By the past 50 yeas ago, whereas deforestation was happened by the government development projects or subsistence activities as migration…
the environment and the economy. Critically discuss the causes of deforestation and solutions to it. Deforestation is the cutting down of a large area of trees and the destruction of forests by people. Forests are what we call an exhaustible resource, one which can be used up if it is not used carefully. Over the last few decades, deforestation has threatened the rainforests with total extinction. To understand why deforestation is such an important issue, you first have to understand why trees…
Rainforest have been declining rapidly over the last few decades. There are various factors responsible for this decline, resulting in serious impacts on the environment and the economy. Critically discuss the causes of deforestations and solutions to it. Deforestation appears to be a major problem in the world today. The disruption of natural rainforest causes damage to 13 million hectares of forest per year (Open University, 2014). Rainforest is a natural resource and can become exhausted if…
DEFORESTATION Trees are one of the most important aspects of the planet we live in. Trees are vitally important to the environment, animals, and of course for us humans. They are important for the climate of the Earth, as they act as filters of carbon dioxide. Forests are known as habitats and shelters to millions of species. However, the trees on our planet are being depleted at a very fast rate. According to some estimates, more than 50 percent (Rainforest Facts, 2012) of the tree cover has disappeared…

It would therefore be prudent to rethink some Canada’s longer-term environmental policies and priorities that are cost effective and sustainable. I have chose reforestation because urbanization is inevitable, reforestation can have a significant long-term impact on climate and air quality and it can also be carried out at minimal cost. Background The typical activities that take place when cities or towns are expanding involves developers simply clearing up the land of it vegetation and then building…
Deforestation is when people cut down whole forests of trees, making it less likely for humans to survive. Deforestation is the permanent destruction of indigenous forests and woodlands. It has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Trees and plants supply oxygen, absorb carbon dioxide, and hold down the soil from washing away and making dangerous landslides. The destruction and cutting down of forests is often done to clear land for farming…
vegetation and plant growth. Also, the impact of the air moisture from tropical forests was not just local, but it has increased rainfall that happens thousands of kilometers away from the forests themselves. Using their current data, predictions and deforestation models, this study suggests that rainfall in the Amazon basin might be reduced to 20 percent by 2050 during the dry seasons. They also predict that reduced rainfall will occur in other tropical areas as forests are reduced, such as the Congo.…
1.0 GENERAL INTRODUCTION Deforestation especially in the tropics has been one of the resultant forces of land use change in the world today and its avoidance has not been realized eligible as a Clean Development Mechanism (CDM) in the Marrakesh Accords. Avoidance of deforestation is not yet eligible as CDM activity mainly because of leakage related issues (Kanninen, et al., 2007). Deforestation involves a permanent process of land-use change which could be a result of forests conversion into croplands…
