What is a problem caused by losses in biodiversity?

The loss of biodiversity has two significant impacts on human health and the spread of disease. First, it increases the number of disease-carrying animals in local populations. … At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease-carrying species.

What are the problems of biodiversity loss?

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.

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.

What are the effects of loss of biodiversity in a region?

Decline in plant production/Decline in number of animal species. Lowered resistance to environmental perturbations such as drought. Increased variability in certain ecosystem processes such as plant productivity/ water use/pest & disease cycles. Species may become endangered/increased rate of species extinction.
