生物多样性丧失

维基百科，自由的百科全书

生物多样性丧失是與生物多樣性破壞有關的現象，例如物种绝灭、棲息地內物种的减少。农业的過度發展會破坏栖息地。[1][2]棲息地內物種減少有可能是暫時現象，也有可能是永久現象。 [3][4][5]有部分觀點認為，人口增长和過度消耗是造成生物多样性丧失的主要因素。[6][7][8][9][10]然而其他科学家对此並不讚同。 [11]气候变化可能也是導致生物多样性丧失的一大因素。 [12] 如果全球变暖的速度加劇，會導致珊瑚礁從地球上消失。 [13][14]

For the first time at a global scale, the report has ranked the causes of damage. Topping the list, changes in land use—principally agriculture—that have destroyed habitat. Second, hunting and other kinds of exploitation. These are followed by climate change, pollution, and invasive species, which are being spread by trade and other activities. Climate change will likely overtake the other threats in the next decades, the authors note. Driving these threats are the growing human population, which has doubled since 1970 to 7.6 billion, and consumption. (Per capita of use of materials is up 15% over the past 5 decades.)

The overarching driver of species extinction is human population growth and increasing per capita consumption.

Conservation biologists standardly list five main direct drivers of biodiversity loss: habitat loss, overexploitation of species, pollution, invasive species, and climate change. The Global Assessment Report on Biodiversity and Ecosystem Services found that in recent decades habitat loss was the leading cause of terrestrial biodiversity loss, while overexploitation (overfishing) was the most important cause of marine losses (IPBES, 2019). All five direct drivers are important, on land and at sea, and all are made worse by larger and denser human populations.

Bibcode:2017Sci...356..260C. PMID 28428391. S2CID 12770178. doi:10.1126/science.aal2011. Research suggests that the scale of human population and the current pace of its growth contribute substantially to the loss of biological diversity. Although technological change and unequal consumption inextricably mingle with demographic impacts on the environment, the needs of all human beings—especially for food—imply that projected population growth will undermine protection of the natural world.

PMID 37722053. doi:10.1073/pnas.2306987120. Current generic extinction rates will likely greatly accelerate in the next few decades due to drivers accompanying the growth and consumption of the human enterprise such as habitat destruction, illegal trade, and climate disruption.

Through examining the drivers of biodiversity loss in highly biodiverse countries, we show that it is not population driving the loss of habitats, but rather the growth of commodities for export, particularly soybean and oil-palm, primarily for livestock feed or biofuel consumption in higher income economies.
