However, massive deforestation for economic development threatens its forests and ecosystems. As of 2015, the country has one of the highest rates of deforestation in the world. [47] Deforestation has directly resulted from poorly managed commercial logging, fuel wood collection, agricultural invasion, and infrastructure and urban development.
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.
The assessment showed that although the rate of deforestation has slowed, the world's forest area continues to decrease. [16] Key findings include: The world has a total forest area of 4.06 billion hectares (ha), which is 31 percent of the total land area. The world's forest area is decreasing, but the rate of loss has declined since 1990.
English: In this paper we afford a quantitative analysis of the sustainability of current world population growth in relation to the parallel deforestation process adopting a statistical point of view. We consider a simplified model based on a stochastic growth process driven by a continuous time random walk, which depicts the technological ...
Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4] [5] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
According to Food and Agriculture Organization's (FAO) Global Forest Resources Assessment 2020, an estimated 420 million hectares (1.0 billion acres) of forest have been lost worldwide through deforestation since 1990, but the rate of forest loss has declined substantially. In the most recent five-year period (2015–2020), the annual rate of ...
[27]: 2321 For example, the decline of sea ice in the Arctic has been accelerating during the early twenty‐first century, with a decline rate of 4.7% per decade (it has declined over 50% since the first satellite records). [28] [29] [30] One well known example of a species affected is the polar bear, whose habitat in the Arctic is threatened ...
Earth Eclipse, [8] a platform of environment research articles, adds the following causes: Acid rain; Pests and diseases; Air pollution. Degradation for this cause is specifically called [citation needed] Waldsterben (German word) or forest death. Forest fragmentation: a large forest is broken up in smaller woods, which destroys the habitat of ...
