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.
How biodiversity loss affects the environment?
Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
What are the causes and consequences of loss of biodiversity?
The numerous factors are responsible for the loss of Biodiversity (Figure 1) such as pollution, habitat loss, hunting, introduction of invasive species, overexploitation of preferred species, climate change, and natural disasters.
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.
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 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 decreasing?
Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.
What is the biggest threat to the loss of biodiversity?
Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
Why is biodiversity important to human biodiversity?
Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.
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.
