They produce oxygen which is vital for living and also provides homes for people and wildlife. Forests play a critical role in mitigating climate change as they work as a carbon sink.

It is estimated that 15 percent of all greenhouse gas emissions come from deforestationaccording to the WWF. Inglobal tree cover loss reached a record of Location Deforestation occurs around the world, though tropical rainforests are particularly targeted.

Deforestation : Definition

If current deforestation levels proceed, the world's rainforests may completely vanish in as little as years, according to National Geographic. The country with the most deforestation is Indonesia. Since the last century, Indonesia has lost at least 39 million acres Though deforestation has increased rapidly in the past 50 years, it has been practiced throughout history.

For example, 90 percent of continental United States' indigenous forest has been removed sinceaccording to the University of Michigan. The World Resources Institute estimates that most of the world's remaining indigenous forest is located in Canada, Alaska, Russia and the Northwestern Amazon basin.

Some other common reasons are: To make more land available for housing and urbanization To harvest timber to create commercial items such as paper, furniture and homes To create ingredients that are highly prized consumer items, such as the oil from palm trees To create room for cattle ranching Common methods of deforestation are burning trees and clear cutting.


These tactics leave the land completely barren and are controversial practices. Clear cutting is when large swaths of land are cut down all at once. A forestry expert quoted by the Natural Resources Defense Council describes clear cutting as "an ecological trauma that has no precedent in nature except for a major volcanic eruption.

Slash and burn agriculture entails cutting down a patch of trees, burning them and growing crops on the land. The ash from the burned trees provides some nourishment for the plants and the land is weed-free from the burning.

When the soil becomes less nourishing and weeds begin to reappear over years of use, the farmers move on to a new patch of land and begin the process again.

Gas molecules that absorb thermal infrared radiation are called greenhouse gases. If greenhouse gases are in large enough quantity, they can force climate change, according to Daley. While oxygen O2 is the second most abundant gas in our atmosphere, it does not absorb thermal infrared radiation, as greenhouse gases do.

Carbon dioxide CO2 is the most prevalent greenhouse gas. CO2 accounts for about Trees can help, though. About billion tons of carbon, 40 times the annual greenhouse gas emissions from fossil fuels, is stored in trees, according to Greenpeace.

The deforestation of trees not only lessens the amount of carbon stored, it also releases carbon dioxide into the air. This is because when trees die, they release the stored carbon. According to the Global Forest Resources Assessmentdeforestation releases nearly a billion tons of carbon into the atmosphere per year, though the numbers are not as high as the ones recorded in the previous decade.

Deforestation is the second largest anthropogenic human-caused source of carbon dioxide to the atmosphere after fossil fuel combustionranging between 6 percent and 17 percent, according to a study published in in Nature.

Carbon isn't the only greenhouse gas that is affected by deforestation. Water vapor is also considered a greenhouse gas.

Changes in their atmospheric concentration will have a direct effect on climate. Deforestation has decreased global vapor flows from land by 4 percent, according to an article published by the journal National Academy of Sciences. Even this slight change in vapor flows can disrupt natural weather patterns and change current climate models.

Other effects of deforestation Forests are complex ecosystems that affect almost every species on the planet. When they are degraded, it can set off a devastating chain of events both locally and around the world. Seventy percent of the world's plants and animals live in forests and are losing their habitats to deforestation, according to National Geographic.Deforestation: Causes, Effects and Control Strategies Sumit Chakravarty1, S.

Oct 02,  · Causes of Deforestation. The most common pressures causing deforestation and severe forest degradation are agriculture, forest fires, mining, infrastructure projects and increased logging.

Some of the causes of deforestation are discussed below.

Harmful Effects Of Deforestation

Agriculture. The conversion of forests into agricultural land is one of the major causes of deforestation. Causes of Deforestation. We already mentioned that one of the causes of deforestation is harvesting natural resources through logging. Wood is a valuable raw material in construction or manufacturing, and the practice of logging prepares the trees for those purposes.

Causes of deforestation and forest degradation Conversion of forests for other land uses, including pulp, palm, and soy plantations, pastures, settlements, roads and infrastructure.

Forest fires: Each year, fires burn millions of hectares of forest worldwide. Video: Deforestation: Definition, Causes & Consequences Deforestation is the clearing of trees without the intent of replacing them or reestablishing a stand of trees. Deforestation means large scale cutting of forests.

The forest lands are converted in to farms, ranches and urban areas through deforestation. Another cause behind deforestation is .
