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.
Why is the worlds loss of biodiversity a concern?
Biodiversity loss affects economic systems and human society. … This lack of biodiversity among crops threatens food security, because varieties may be vulnerable to disease and pests, invasive species, and climate change.
Why is loss of biodiversity bad for the environment?
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 is biodiversity loss important?

Losing one might not be a disaster, but each loss adds to the likelihood of a serious problem. … Ecosystems weakened by the loss of biodiversity are less likely to deliver those services, especially given the needs of an ever-growing human population.

For humans that is worrying.
What are the negative effects of biodiversity loss?
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 negative effects of biodiversity?
destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
How does biodiversity loss affect the economy?
Food production relies on biodiversity for a variety of food plants, pollination, pest control, nutrient provision, genetic diversity, and disease prevention and control. … Decreased biodiversity can lead to increased transmission of diseases to humans and increased healthcare costs.
What are the cause and effect of loss of biodiversity?
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.
