Why is lack of biodiversity a problem?
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. For humans that is worrying.
What are the negatives of low biodiversity?
Low diversity for any species can be defined as the presence of a lesser variety of successful individuals such that they create an unstable and unhealthy ecosystem which is more likely to collapse in front of complex food webs and natural hurdles and thus possibly lead to extinction of the species.
What are the effects of biodiversity?
These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
Why is biodiversity at risk?
Much of the Earth’s biodiversity, however, is in jeopardy due to human consumption and other activities that disturb and even destroy ecosystems. Pollution, climate change, and population growth are all threats to biodiversity. These threats have caused an unprecedented rise in the rate of species extinction.

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.
