Potential for biodiversity loss from future fossil fuel extraction: Proportions of oil and gas field area overlapping with Protected Areas (PAs) (gray polygons) of different IUCN Protected Area management categories by UN regions: North America (a), Europe (b), West Asia (c), LAC (d), Africa (e), and Asia Pacific (f). Absolute area of overlap ...
Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [ 41 ] and some species are now only breeding in modified habitat. [ 42 ]
However, biodiversity loss is occurring rapidly on a global scale – since 1970, wildlife populations declined by 69%, on average, between 1970 and 2018. [28] Biodiversity loss and its potential implications on ecosystem functioning, ecosystem services, the global economy, and wider society have gained increasing attention. [28]
In the ocean, overfishing is a major cause of species loss. [ 16 ] [ 27 ] Some 300–400 million metric tons (660–880 billion lb) of heavy metals , solvents , toxic sludge , and other wastes per year enter the water cycle from industrial facilities.
One solution to the problem of habitat fragmentation is to link the fragments by preserving or planting corridors of native vegetation. In some cases, a bridge or underpass may be enough to join two fragments. [28] This has the potential to mitigate the problem of isolation but not the loss of interior habitat.
Reforestation was conducted as a part of afforestation due to inabilities of self-recovering by the natural land itself due to serious soil pollution and loss of woods consequence in loss of soils for plants to grow, thus needing artificial efforts involving introducing of healthy soils from outside. Starting from around 1897, about 50% of once ...
Sustainable Development Goal 15 (SDG 15 or Global Goal 15) is about "Life on land".One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". [1]
A 2019 UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. [ 38 ] [ 39 ] Conservation of a select species are often prioritized on several factors which include significant economic and ecological value, as well as desirability or attractiveness. [ 40 ]
