When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide.
Deforestation of Our Rainforests
Averaged over — , global loss of tropical forests contributed about 4. Whilst forests are important carbon sinks, meaning they draw down carbon dioxide from the atmosphere, the carbon stored in these sinks is part of an active, relatively quick carbon cycle.

As living things including trees die and decay, the carbon that they once stored is released back into the atmosphere. By contrast, carbon stored underground in the form of fossil fuels such as coal, oil and gas, is much more stable, and is part of a much slower carbon cycle. Without the influence of humans burning these fossil fuels for energy, this carbon would be unlikely to reach the atmosphere. When fossil fuels are burned, carbon from dead and decayed plants, animals and phytoplankton that lived hundreds of millions of years ago before dinosaurs existed , is released into the atmosphere in the form of carbon dioxide.
Haze from forest fires blankets a an area of deforestation. Without trees, the soil is free to wash or blow away, which can lead to vegetation growth problems. The WWF states that scientists estimate that a third of the world's arable land has been lost to deforestation since After a clear cutting, cash crops like coffee, soy and palm oil are planted. Planting these types of trees can cause further soil erosion because their roots cannot hold onto the soil. Both countries share the same island, but Haiti has much less forest cover than the Dominican Republic.
As a result, Haiti has endured more extreme soil erosion, flooding and landslide issues. Life quality : Soil erosion can also lead to silt entering the lakes, streams and other water sources. This can decrease local water quality and contribute to poor health in populations in the area. The disturbance of native people: Many native tribes live in the rainforests of the world, and their destruction is the destruction of these peoples' homes and way of life. For example, the film "Under the Canopy" takes a look at the Amazon rainforest and the people who live there, including an indigenous guide named Kamanja Panashekung.
Sanjayan, Conservation International's executive vice president and senior scientist, said in a statement. Many believe that to counter deforestation, people simply need to plant more trees. Though a massive replanting effort would help to alleviate the problems deforestation caused, it would not solve them all.
Essay on Deforestation: 8 Selected Essays on Deforestation
Reforestation won't completely fix the damage, though. For example, Daley points out that forests cannot sequester all of the carbon dioxide humans are emitting to the atmosphere through the burning of fossil fuels and a reduction in fossil fuel emissions. It is still necessary to avoid buildup in the atmosphere. Reforestation will not help with extinction due to deforestation, either. In addition to reforestation, some other tactics are being taken to counteract or slow deforestation. Some of them include shifting the human population to a plant-based diet. This would lower the need for land to be cleared for raising livestock.
Global Forest Watch has also initiated a project to counteract deforestation through awareness. The organization uses satellite technology, open data and crowdsourcing to detect and alert others of deforestation. Their online community is also encouraged to share their personal experiences and the negative effects of deforestation. Live Science. In the Northern Hemisphere, to were the warmest year period of the last years.
A large contributing factor to deforestation is the lumber industry.
In addition, the increasing demand for low costing timber products only supports to the lumber company to continue logging. Deforestation is a main concern in tropical rainforest since it is home to millions of animals in the biodiversity. Not only does the lumber industry impact deforestation but also the environment due to deforestation drives on climate change. Urbanisation is the process of clearing a large area of land to build more living space. As a result of expanding land for residential and urban purposes, there is a significant amount of forest loss .
The Negative Effects of Deforestation on the World
As the human population continue to increase throughout the years, the demand and needs for necessities also increase. This means that more land is needed to be cleared in order to build more homes, recreational uses, and agriculture. In addition, this also promotes the industrialisation to grow and require more land to provide consumers with the food products demanded.
Livestock ranching requires large portions of land to raise herds of animals and livestock crops for consumerism needs. Livestock ranching originated in Texas between and which were mainly driven by Mexican cowboys. After the civil war, Texans begin rounding up the cattle and selling them around states such as California and New Orleans. According to Greenpeace, a non-governmental global environmental organisation, the cattle industry is responsible for a significant amount of methane emission.
This is because speculators burn huge areas of rainforest for pasture.
Long and Short Essay on Deforestation in English
The number one largest cause of deforestation and acute degradation is agriculture. A continued increase of demand for timber and agricultural products are only critical indirect drives. Forest are giving way to plantation for coffee, tea, palm oil , rice, rubber , and many other highly demanded products. These rising demands for certain products and global trade arrangements causes forest conversions , which ultimately leads to soil erosion.
The top soil oftentimes erodes after forests are being cleared which leads to sedimentation increase in rivers and streams.
Over time, agricultural land degrades and becomes almost useless causing producers to find new productive lands. A study conducted by the National Science Foundation found that biodiversity and genetic diversity are codependent—that diversity among species requires diversity within a species, and vice versa.

Additionally, cutting down trees plays a role in a positive feedback loop centred around climate change on a much larger scale, as studies are finding. Burning or cutting down trees reverses the effects of carbon sequestration and releases greenhouse gases including carbon dioxide into the atmosphere.
"The Impact of Deforestation on Global Warming"
This results in an increase in the absorption of light energy from the sun in the form of heat, enhancing global warming. Trees are a major source of carbon. This implies having a hotter and drier climate, and a longer dry season. Reforestation is the natural or intentional restocking of existing forests and woodlands that have been depleted, usually through deforestation.
It is the reestablishment of forest cover either naturally or artificially. Afforestation is the planting of trees where there was no previous tree coverage. Degradation of forest ultimately leads to a decrease in oxygen and a sufficient increase of carbon dioxide.
In order to make up for the loss, more trees are being planted. As a result, the amount of carbon dioxide in the atmosphere could significantly decrease . According to a scientific research, plantation forest could absorb more carbon dioxide than natural forest since they grow faster leading to a higher absorbance rate. The process is usually encouraged by governments because they want it to lead to a decrease in carbon dioxide and because it increases the aesthetics of the area. Although, it could lead to infringing upon ecosystems and create complications in environments that previously did not have tree coverage or forests.
Although China has set official goals for reforestation, these goals were set for an year time horizon and were not significantly met by
