Trees are cut and the land is converted into a pasture for cattle grazing. According to one report, an estimated 70 percent of deforestation in the Amazon basin can be attributed to cattle ranching. Using these numbers, cattle ranching in the Amazon has resulted in the loss of an area larger than the state of Washington. It has the largest commercial cattle herd of approximately — million head.
From helping to mitigate climate change; providing homes for many species of plants and animals some endemic to forested regions ; providing food, medicine and livelihoods for people around the globe; to the intrinsic values of forests, these essential ecological powerhouses are irreplaceable—and at risk.
Yet, despite everything forests do for the planet, they are being cut down at an alarming rate. Every year thousand square miles of forest are lost to deforestation, which is equal to an astounding 48 football fields of forest disappearing every minute.
Although there is much cause for concern when considering the degradation of forests worldwide, many still have hope that with the right changes in policy and perception, forests can still be saved. What is Main causes deforestation Deforestation? There are many factors that contribute to deforestation, each with its own causes and negative environmental impacts.
Deforestation Fronts Revealed Agriculture Agriculture is one of the most significant causes of deforestation.
The first form of agriculture that will be examined is slash-and-burn agriculture.
Slash-and burn agriculture can be a sound agricultural practice in many instances, and has long been practiced by many aboriginal communities. Slash-and-burn agriculture is responsible for the loss of around 50 acres of land every hour worldwide.
One of the issues with slash and burn is that fires intentionally set can unintentionally spread throughout the forest.
CAUSES OF DEFORESTATION Deforestation is the product of the interaction of the many environmental, social, economic, cultural, and political forces at work in any given region. The mix of these forces varies from decade to decade, and from country to country. As a consequence, generalizations are dangerous. In most cases, deforestation is a process that involves a competition . Desertification Effects, Causes, And Examples List Desertification is a process of land-degradation by which a region becomes progressively drier and drier.

When fire spreads to unintended areas, the protective forest canopy is destroyed. The resulting sun exposure to the forest floor intensifies the existing fire.
For example, in the Amazon rainforest the seasons are so extreme, in terms of precipitation, that there are just two named seasons: Although there are many, complex issues surrounding the use of slash-and-burn agriculture in the Amazon, the underlying rationale for the practice is very simple: For impoverished farmers, the simplest solution to this problem is to cut down the trees, and burn what remains.
Unfortunately, this is a short term solution. The soil only stays nutrient rich for so long, about two years, after this time, the nutrients from the burned biomass are used up.
When this happens, farmers pack up and move on to the next section of the rainforest, leaving their farmland behind for others to use for cattle rearing, or abandonment. Furthermore, slash-and-burn agriculture on this scale can also have devastating affects for the biodiversity in the area.
With large areas of land being incinerated, many animal habitats are lost in the fire. This pushes animals out of the forest, decreasing biodiversity, and increasing the number of endangered and extinct animal species. Raising Cattle Cattle ranching has a massive impact on forests around the world, particularly tropical rainforests like the Amazon.
Many farmers use deforested areas of land to raise cattle; however, it might surprise you to learn that corporations do this on a much larger scale. Fast food companies have been contributing to deforestation in places like the Amazon rainforest for quite some time, and only in relatively recent years have their actions been acknowledged by mainstream media.
Companies that have been deforesting the rainforest in order to raise cattle for their hamburgers include: Although some of these companies have made promises to be more environmentally conscious, some, such as Burger King and Pizza Hut, have made no plans to move away from this harmful and unnecessary form of animal agriculture.
Amazon destruction Logging Logging is also a common cause of deforestation as trees are cut down to use for paper products. There are several different types of logging: In some cases, areas of forest that have been clear cut are candidates for remediation.
Remediation of clear cut areas of forest, however, comes with its own issues. Often times mono-planting is a go-to remediation plan, which is to say that only one species of tree is planted in that area.
All of the biodiversity lost to clear cutting is not remedied by mono-planting.Found in everything from shampoo to donuts, palm oil is now the most common vegetable oil in the world—and also one of the world's leading deforestation drivers.
Deforestation means large scale cutting of forests which leads to extinction of various species, relocation of wildlife animals, global warming etc. Have a look at some of . The main causes of tropical deforestation are explained in this article.

The Brazilian Amazon region is an unique area. It holds the world's largest rainforest (Butler b).This area is the one of the highly deforested areas in the world (Butler a).Some reasons for this are widespread agricultural and logging purposes.
