How will changes in pathogen biodiversity and range affect human health?

In addition, changes in biodiversity can affect the transmission of infectious disease to humans, particularly vectorborne diseases such as malaria and Lyme disease. … Research on these links can have an important impact on our view of biodiversity and how we manage resources to protect human and ecosystem health.

How does biodiversity affect human health?

Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.

How can biodiversity affect diseases spread to human populations?

In principle, loss of biodiversity could either increase or decrease disease transmission. However, mounting evidence indicates that biodiversity loss frequently increases disease transmission. In contrast, areas of naturally high biodiversity may serve as a source pool for new pathogens.

How does biodiversity loss affect infectious diseases in human?

Several studies suggest that with the loss of biodiversity the transmission of diseases increases (Keesing et al. 2010). Thus biodiversity loss causes the loss of an important ecosystem service: buffering the spreading of infectious diseases to humans, animals and plants (Pongsiri et al. 2009).

How does biodiversity affect disease?

Biodiversity probably has little net effect on most human infectious diseases but, when it does have an effect, observation and basic logic suggest that biodiversity will be more likely to increase than to decrease infectious disease risk.

What is biodiversity and why it is important for human life?

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 provide people’s medical needs?

Diets based on a diversity of food species promote health, and can help to protect against disease by addressing the problem of micronutrient and vitamin deficiencies. Loss of agricultural biodiversity can therefore threaten health, livelihood sustainability and our future security of food and nutrition.

Why is maintaining global biodiversity important to human health?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

What happens to an ecosystem due to human activity?

Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.

How does biodiversity affect zoonotic diseases?

Impacts of Biodiversity Loss on Zoonotic Diseases

Recent research shows that fast-lived species are more likely to transmit zoonotic pathogens (61). Together, these processes are likely to lead to increases in the abundance of zoonotic reservoirs when biodiversity is lost from ecological systems.

Does biodiversity loss aggravate transmission of infectious disease spread by animals to humans?

Do biodiversity losses aggravate transmission of infectious diseases spread by animals to humans? The jury is still out but several scientists say there is a “biodiversity dilution effect” in which declining biodiversity results in increased infectious-disease transmission.

What are the leading human caused environmental practices driving the rise in prevalence of infectious zoonotic diseases?

These drivers include landuse changes (e.g., deforestation, agricultural encroachment, and urban sprawl), climate change, and more subtle products of anthropogenic change such as biodiversity loss (IOM, 1992; Krause, 1992, 1994; Morse, 1993; Daszak et al., 2000, 2001; Anderson et al., 2004).

How does biodiversity decrease disease?

Disease ecologists fervently debate whether biodiversity loss leads to an increased disease risk. Now, a new study offers some answers. Biodiversity is disappearing at an alarming rate as infectious diseases increasingly spill over from wildlife to humans.
