Trees are cut down for wood, waiting to be transported and sold. Deforestation is the intentional logging of wooded land. Throughout history and in modern times, forests have been razed to make room for agriculture and animal grazing, and to obtain wood for fuel, manufacturing and construction. When people want to use a piece of land, for agriculture, development or some other purpose, they cut down trees in that area.
Food production is the most common reason for clearing. This land clearing, also known as deforestation, often occurs so that people can raise livestock or other sources of meat for consumption, or grow plants for the production of palm oil or soybean. Today, most deforestation occurs in the tropics, but wherever land clearing occurs, it affects our planet's climate.

is a fundamental pressure on the environment.It causes the loss, fragmentation and degradation of native vegetation and a variety of impacts on our soils (for example,. Erosion and loss of nutrients), waterways and coastal regions (for example,. Climbing has a major impact on the health of rivers and coastal ecosystems. It increases erosion and runoff of sediments, nutrients and other pollutants into coastal waters, causing damage to coral reefs and other marine ecosystems, such as seagrass beds.
Increased nutrients in rivers and streams can cause outbreaks of toxic algae. Deforestation is the large-scale logging of land, usually for agriculture, industry or transport. Livestock operations occupy 45 percent of the world's surface area, and an additional 10 percent is dedicated to the cultivation of feed for these animals. Nearly 60 percent of the world's arable land is used solely for beef production, requiring large amounts of land for livestock grazing and growing feed such as soy.
Soy production has doubled in the last 20 years, largely due to the expansion of livestock farming. Every year around 1.2 million acres of land are cut down for soy production in tropical climates, and that number will continue to rise if the world does not reduce animal protein consumption. Soy production for animal feed is another silent competitor that has doubled in the last 20 years as a result of increased demand for meat and dairy products. Of the 346.02 million metric tons of soy produced each year worldwide, 80 percent is used for animal consumption.
Around 60 million acres are dedicated exclusively to soy production in Brazil, and that number continues to increase along with the growing demand for meat. In the last 40 years, at least 20 percent of the Amazon rainforest has been destroyed. At least 20 percent of the Amazon has already been cleared and about 80 percent of that land has been used for livestock. According to environmental researcher Nicholas Carter, “Animal agriculture is the main cause of biodiversity reduction, which is mainly due to deforestation.
The Cerrado area of Brazil, the savannah with the highest biological diversity in the world, is deforested by the production of half of the country's soy crops. The wildlife diversity of the area is threatened by the rapidly increasing production of livestock feed and the 40 million head of livestock that this region produces each year. The Amazon rainforest is not the only region that loses its plant and animal habitats to man-made threats. Indonesia's rainforests cover only 1 percent of the planet's surface, but contain up to 20 percent of known species of plants, mammals and birds.
If every American were to reduce their meat consumption by just a quarter, 82 million metric tons of greenhouse gas emissions would be saved every year. Eliminating meat altogether from the US diet would quadruple that number. Agriculture, livestock grazing, mining and drilling combined account for more than half of all deforestation. Forest practices, forest fires and, to a small extent, urbanization account for the rest.
In Malaysia and Indonesia, forests are cut down to make way for palm oil production, which can be found in everything from shampoos to salty. In the Amazon, livestock and farms, particularly soy plantations, are the main culprits. Logging operations, which provide the world's wood and paper products, also cut down countless trees every year. Loggers, some of them acting illegally, also build roads to access increasingly remote forests, leading to further deforestation.
Forests are also cut down as a result of increasing urban sprawl as land for housing is developed. It is also regulated by Development Control and Environmental Planning Instruments (EPIs) under the Land Use Planning Act, namely the Environmental Planning and Assessment Act 1979 (NSW). Without trees, a process called evapotranspiration, the combined evaporation of water from the surface of the earth and plants, and the release of water from plant leaves would be interrupted. Common objectives include creating healthier ecosystems, improving biodiversity and mitigating the heat island effect through tree retention and scheduled tree planting programs.
Uses an information-theoretical approach to compare and evaluate alternative hypotheses with respect to approximate drivers of clearing. In the immediate vicinity, logging destroys and fragments habitats, endangers animals, increases soil erosion, contributes to pollution, increases the risk of floods and even aggravates the effects of climate change. The more people clean the land, the less available habitat animals have to use for survival and reproduction, resulting in a decline in the population of many species. Land clearing is one of Australia's major sources of greenhouse gas emissions, contributing approximately 12 percent to Australia's total emissions in 1998. A series of institutional incentives for agriculture increased the economic gain from land clearing, with cheap land offers together with venture capital in the form of loans or tax concessions.
Since the 1980s, the rate of clearing has declined due to changes in attitude and increased awareness of the damaging effects of clearing. As land cover is crucial to the condition of the land, clearing places significant pressure on the condition of the land. Obviously, clearing has a strong impact on the environment at the local level, but it also has global repercussions. Agricultural expansion accounts for nearly 30 percent of this estimate, including growing crops for livestock and clearing land for grazing.
In New South Wales, much of the remaining forests and forests have been cleared, due to the high productivity of the land. . .
