- In the Amazon, industrial-scale cattle ranching and soybean production for world markets are increasingly important causes of deforestation, and in Indonesia, the conversion of tropical forest to commercial palm tree plantations to produce bio-fuels for export is a major cause of deforestation on Borneo and Sumatra.he single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors.

Long Term Negative Effects of Deforestation in the Amazon Essay example The Amazon rainforest will disappear is not an assumption. It absolutely will be happen if people keep on deforesting the Amazon rainforest for many different demands. Huge amounts of area in Amazon were deforested because of agricultural pursuits. Also, the deforestation rate has increased in other ways, such as obtain more land for living and excessive uses of wood. Therefore, a large amount of trees were cut down and led to forest destruction.

While examining Figure 1, it is important to compare the original forest cover with the present forest cover; the numbers are dreadfully surprising.ack to Table of Contents Causes: Figure 3. The major causes of tropical deforestation (Rainforest Alliance, 1999). Agriculture, the logging industry, fuelwood collection and cattle ranching directly consume the largest amounts of rainforest land throughout the world, respectively (Figure 3).

What Are the Effects of Deforestation? Quick Answer. The World Wildlife Fund lists reduced biodiversity, increased greenhouse gas emissions, disruptions in the water cycle and increased erosion as the primary effects of deforestation. Millions of people directly rely on forests for subsistence and the loss of forests poses a risk to their lifestyles.

- Answer by Luke204. Confidence votes 80. Deforestation causes water pollution because when there are no trees left to block the rain fall the rain falls directly on to the soil and washes it in to the rivers, which take it on to the seas and oceans.The soil may contain chemicals that pollute the water.ack of awareness of humans is the primary cause of water pollution. Also dumping of garbage, oil spills, dumping of nuclear waste and passing waste in water sources are causes of water pollution. Lack of awareness of humans is the primary cause of water pollution.

- Deforestation. The world’s forests, especially rainforests, are vital in that they provide unique habitats for many unique species. They also act as a ‘carbon sink’, trapping away lots of carbon in their biomass [biomass: The dry mass of an organism.] that was previously absorbed for photosynthesis. [photosynthesis: A chemical process used by plants and algae to make glucose and oxygen from carbon dioxide and water, using light energy.

Deforestation Effects, Causes, And Examples: Top 10 List Deforestation also has a profound effect on many of the world’s water cycles. Reduced vegetation and ground-cover leads to a general drying-out of the soil — which over time leads to lower levels of rain. And, eventually, leads to significant soil erosion and desertification.

10 Tips to Help Prevent Tropical Rainforest Deforestation The deforestation of tropical rainforests is leading to a phenomenal loss of global biodiversity and the consequent loss of medicines, foods and other resources. Deforestation is also leading to localized changing weather patterns, flooding and an increase in carbon emissions and climate change.

Top Five Causes of Species Extinction Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year.The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation.he most dramatic impact is a loss of habitat for millions of species. Seventy percent 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.

It is estimated that 15% of all greenhouse gas emissions are the result of deforestation. Deforestation is a particular concern in tropical rainforests because these forests are home to much of the world’s biodiversity.For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching.educed Biodiversity. About 80% of the world’s documented species can be found in tropical rainforests—some of the forests most vulnerable to deforestation. When species lose their forest homes, they are often unable to subsist in the small fragments of forested land left behind.

Deforestation 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.thers state that tropical rainforest deforestation is contributing to the ongoing Holocene mass extinction. The known extinction rates from deforestation rates are very low, approximately 1 species per year from mammals and birds which extrapolates to approximately 23,000 species per year for all species.
