Causes of Deforestation

Humans constantly clean forests for their benefit, but in the past the process is late and only limited areas are usually cut down by self-sufficiency agriculture. Today, however, humans are becoming more efficient by using our cutting-edge technology and machinery to wipe out forests, and we are trying to make profits furiously in the near future. Ranch established a meadow in the tropical rainforest for many fast food companies. A large area of ​​tropical rainforest burned out to form grasslands and cattle were brought to the grass for grazing.

Forest logging means loss of forest habitat due to natural causes or artificial causes. Forest fires such as forest fires, forest fires, volcanic eruptions and glacier effects are also related to the causes of human-related deforestation, such as mining, logging and farming by agricultural deforestation. Cow breeding is the main cause of deforestation in Brazil. This is a fact at least since 1970. This is because in Brazil the price and demand of Brazilian beef has been raised by eradication of foot and mouth disease, developers and ranchers can enter the forest areas that can not be accessed by Amazon, the developers cut down the forests It is because it is enough to put it on. Some cows can gain ownership of Amazon land

Forest deforestation eradicates the world's forests on a large scale around the world and causes loss of many lands. One reason for deforestation is to clean the land for meadows and crops. According to UK environmental conservation activist Norman Myers, 5% of deforestation is due to meadow, 19% is due to overcutting, 22% is due to growth of palm oil plantation, 54% is due to slash-and-burn slash . . Forest loss is the driving force for climate change, causing millions of species to lose habitat. The tree functions as a carbon sink. In other words, it absorbs carbon dioxide, which is an unnecessary greenhouse gas which is absorbed from the atmosphere. When trees are removed, carbon dioxide is released into the atmosphere and few trees absorb the increasing carbon dioxide in the air. Thus, deforestation worsens climate change.

Forest loss is the cause of global warming and is often quoted as one of the main reasons for increasing greenhouse effect. Tropical deforestation accounts for about 20% of global greenhouse gas emissions. According to the Intergovernmental Panel on Climate Change, deforestation mainly in the tropics can account for one-third of total human-originated carbon dioxide emissions. However, in recent calculations, carbon dioxide emissions (excluding peatland emissions) from deforestation and forest degradation account for about 12% of total anthropogenic carbon dioxide emissions, ranging from 6% to 17% It has been shown to be. Forest logging keeps carbon dioxide in the atmosphere. When carbon dioxide accumulates, an emissive layer from the sun is formed in the atmosphere. Radiation is converted to heat, which causes global warming. This is called the greenhouse effect. Deforestation can also release carbon stocks in the soil.
