The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
The Report examined the rate of decline in biodiversity and found that the adverse effects of human activities on the world's species is "unprecedented in human history": [14] one million species, including 40 percent of amphibians, almost a third of reef-building corals, more than a third of marine mammals, and 10 percent of all insects are ...
This includes its role in providing ecosystem services - the benefits that humans get from ecosystems. Biodiversity plays a major role in the productivity and functioning of ecosystems, affects their ability to provide ecosystem services. [2] For example, biodiversity is a source of food, medication, and materials used in industry. Recreation ...
Some of the health issues influenced by biodiversity include dietary health and nutrition security, infectious disease, medical science and medicinal resources, social and psychological health. [166] Biodiversity is also known to have an important role in reducing disaster risk and in post-disaster relief and recovery efforts. [167] [168]
A trade-off between human health and the "health" of nature has been termed the "health paradox" [45] and it illuminates how human values drive perceptions of ecosystem health. Human health has benefited by sacrificing the "health" of wild ecosystems, such as dismantling and damming of wild valleys, destruction of mosquito-bearing wetlands ...
The findings of TEEB (Interim Report) were largely in three areas—the economic size and welfare impact of losses of ecosystems and biodiversity, the strong links between biodiversity conservation and ecosystem health on the one hand and poverty elimination and the achievement of Millennium Development Goals on the other, and the ethical ...
Human activities are affecting the capacity of ecosystems to provide these goods and services. [18] [19] Drivers of biodiversity loss and decline in ecosystem functioning include climate change, deforestation, desertification and land degradation, freshwater decline, overexploitation, stratospheric ozone depletion, and pollution.
According to the biodiversity hypothesis, reduced contact of people with natural environment and biodiversity may adversely affect the human commensal microbiota and its immunomodulatory capacity. The hypothesis is based on the observation that two dominant socio-ecological trends – the loss of biodiversity and increasing incidence of ...
