The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. [ 1 ] [ 2 ] [ 3 ] These activities include habitat destruction [ 4 ] (for example deforestation ) and land use intensification (for example monoculture farming).
In these areas, the loss of grass due to the presence of trees and other shrubbery leads to more erosion than when trees are removed. [207] Soils are reinforced by the presence of trees, which secure the soil by binding their roots to soil bedrock. Due to deforestation, the removal of trees causes sloped lands to be more susceptible to landslides.
Other effect of deforestation in the Amazon rainforest is seen through the greater amount of carbon dioxide emission. The Amazon rainforest absorbs one-fourth of the carbon dioxide emissions on Earth, however, the amount of CO 2 absorbed today decreases by 30% than it was in the 1990s due to deforestation. [35]
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, pollution, and biodiversity loss are only among a few causes. “Since the Industrial Revolution , we have been putting pressure on nature by using its resources without supporting ...
Forest loss is acute in Southeast Asia, [42] the second of the world's great biodiversity hot spots. [43] According to a 2005 report conducted by the FAO, Vietnam has the second highest rate of deforestation of primary forests in the world, second to only Nigeria . [ 44 ]
The loss and fragmentation of habitats makes it difficult for migratory species to find places to rest and feed along their migration routes. [24] The effects of current fragmentation will continue to emerge for decades. Extinction debts are likely to come due, although the counteracting immigration debts may never fully be paid.
Deforestation in the DRC leads to biodiversity loss, soil erosion and contributes to climate change. The DRC is one of 17 megadiverse countries, with a significant wildlife that is harmed by habitat loss. For example, 60% of the forest elephant population drop is due to the loss of shelter caused by illegal logging. [6]
