Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
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]
Scientific understanding of the process of extinction is insufficient to accurately make predictions about the impact of deforestation on biodiversity. [229] Most predictions of forestry related biodiversity loss are based on species-area models, with an underlying assumption that as the forest declines species diversity will decline similarly ...
The authors have coined the expression "dead species walking" for the more than 500,000 species that are not yet extinct but, due to changes in, or reduction of, their habitats, have no chance of long-term survival. [18] A 2002 satellite image showing deforestation due to palm oil farming in Malaysian Borneo.
Habitat loss, which can occur through the process of habitat fragmentation, is considered to be the greatest threat to species. [14] But, the effect of the configuration of habitat patches within the landscape, independent of the effect of the amount of habitat within the landscape (referred to as fragmentation per se [ 5 ] ), has been ...
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 ]
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]
Loss of biodiversity: This is the decline in the number and variety of plant and animal species. Loss of biodiversity can have a number of negative impacts, including the disruption of food chains and the loss of ecosystem services. Land conversion can also have a number of negative economic impacts, [27] including:
