Deforestation in the city of Rio de Janeiro in Brazil's Rio de Janeiro state, 2009. Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use.
Deforestation is clearing the Earth's forests on a large scale worldwide and resulting in many land damages. One of the causes of deforestation is clearing land for pasture or crops. According to British environmentalist Norman Myers , 5% of deforestation is due to cattle ranching , 19% due to over-heavy logging , 22% due to the growing sector ...
For example, in the past, it could take a long time to log a small amount of trees using only saws. Due to better technology, the rates of deforestation have greatly increased. [6] Overconsumption has created a high demand for natural resources, further exacerbating natural resource exploitation [7]
Deforestation in the United States was affected by many factors. One such factor was the effect, whether positive or negative, that the logging industry has on forests in the country. Logging in the United States is a hotly debated topic as groups who either support or oppose logging argue over its benefits and negative effects.
A consequence of deforestation is typically large-scale erosion, loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil.
Tropical deforestation: In most cases of tropical deforestation, three to four underlying causes are driving two to three proximate causes. [19] This means that a universal policy for controlling tropical deforestation would not be able to address the unique combination of proximate and underlying causes of deforestation in each country. [19]
Deforestation causes many threats to wildlife as it not only causes habitat destruction for the many animals that survive in forests, as more than 80% of the world's species live in forests but also leads to further climate change. [8] Deforestation is a main concern in the tropical forests of the world.
Reducing emissions from deforestation and forest degradation (REDD+) is an international voluntary climate change mitigation approach to curb deforestation and forest degradation. This mechanism makes part of the United Nations Framework Convention on Climate Change (UNFCCC) since 2005.
