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.
What is the common cause of biodiversity loss?
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.

What are the effects of loss of biodiversity class 12?
A rapid environment change typically causes mass extinctions. -A decline in plant production will be a loss of biodiversity that will affect the ecosystem on earth. -A low resistance to environmental perturbations will eventually make a species less adaptable to a given environment and finally loss of biodiversity.

What is biodiversity loss quizlet?
Biodiversity = The biological diversity of life. … Measured on a genetic, taxonomic, ecological and spacial level. Often also measured by abundance (population, interactions, turnover), species richness (number of species), and function.
