Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
[10] [11] The relationship between deforestation and climate change is one of a positive (amplifying) climate feedback. [12] The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth.
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.

On the contrary, forest degradation may start and go on without showing clear effects. It is difficult to measure and even the very term is controversial. In a paper [ 4 ] submitted to the XII World Forestry Congress , 2003, Jean-Paul Lanly states: "The situation is even less satisfactory regarding forest degradation due in particular to the ...
Deforestation is the main land use change contributor to global warming, [126] as the destroyed trees release CO 2, and are not replaced by new trees, removing that carbon sink. [127] Between 2001 and 2018, 27% of deforestation was from permanent clearing to enable agricultural expansion for crops and livestock.
In 2005, Nigeria had the highest rate of deforestation in the world, according to the Food and Agriculture Organisation of the United Nations (FAO). [6] Deforestation in Nigeria is caused by logging, subsistence agriculture, and the collection of wood for fuel. According to the gfy, deforestation has wiped out nearly 90% of Africa's forest.
Most deforestation today occurs in tropical forests. The vast majority of this deforestation is because of the production of four commodities: wood , beef , soy , and palm oil . [ 15 ] Over the past 2,000 years, the area of land covered by forest in Europe has been reduced from 80% to 34%.
