Biodiversity is essential for ecosystem services and hence for human well-being. … At the same time, however, these losses in biodiversity and associated changes in ecosystem services have caused other people to experience declining well-being, with some social groups being pushed into poverty.
Biodiversity loss is more than an environmental problem, it is a development, economic, social and moral issue. … They clearly demonstrate that biodiversity is as much a development, economic, social and moral issue as an environmental issue.
How does biodiversity affect society?
Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply.
Economic and societal effects
The loss of biodiversity among these critical natural resources threatens global food security and the development of new pharmaceuticals to deal with future diseases. Simplified, homogenized ecosystems can also represent an aesthetic loss.
What are the negative effects of biodiversity loss?
Loss of biodiversity undermines the ability of ecosystems to function effectively and efficiently and thus undermines nature’s ability to support a healthy environment. This is particularly important in a changing climate in which loss of biodiversity reduces nature’s resilience to change.
Why biodiversity loss is an important global issue?
Biodiversity loss disrupts the functioning of ecosystems, making them more vulnerable to perturbations and less able to supply humans with needed services. … To stop ecosystem degradation, the full contribution made by ecosystems to both poverty alleviation efforts and to national economies must be clearly demonstrated.
How does biodiversity loss affect diversity?
Loss of biodiversity will impact the number of pharmaceuticals available to humans. Crop diversity is a requirement for food security, and it is being lost. The loss of wild relatives to crops also threatens breeders’ abilities to create new varieties.
How does the loss of species impact the environment?
At higher levels of extinction (41 to 60 percent of species), the effects of species loss ranked with those of many other major drivers of environmental change, such as ozone pollution, acid deposition on forests and nutrient pollution.
What are the consequences of species loss?
Scientists say their loss has played a role in pandemics, fires, the decline of valued species and the rise of invasive ones, the reduction of ecosystem services, and decreased carbon sequestration.
Biodiversity gives resilience—from the microbes that contribute to the formation of the human biome to the genes that help us adapt to stress in the environment—supports all forms of livelihoods, may help regulate disease, and is necessary for physical, mental, and spiritual health and social well-being.
How does biodiversity loss impact natural selection and evolution?
If there is sufficient biodiversity when an environmental change occurs some variations may be adapted to the changing environment. These variation will survive while natural selection, selects the poorly adapted variations for extinction. Those biodiversity will lead to a change in the population.
What are the causes and effects of biodiversity loss?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.
How does loss of biodiversity affect sustainable development?
As biodiversity is lost, there is a risk that some thresholds will be passed, undermining the functioning of the earth system. Conversely, the conservation and sustainable use of biodiversity contributes to sustainable development and mitigation and adaptation to climate change.
