Biodiversity loss is linked to increased transmission of infectious diseases. Reduced biodiversity may increase disease transmission by altering host and vector abundance, host behavior, or host condition. High biodiversity can reduce pathogen transmission by increasing host diversity, which can dilute pathogen prevalence. However, biodiversity loss can also increase disease transmission by reducing competition and predation on hosts, increasing host density, or by removing species that buffer pathogen transmission. Biodiversity loss is associated with increased risk of emerging infectious diseases, as species diversity can influence the emergence of new pathogens. High biodiversity areas may serve as reservoirs for new pathogens, while biodiversity loss can increase the risk of disease transmission. Biodiversity loss is also linked to reduced ecosystem services, including resistance to drought and nutrient cycling. Preserving biodiversity can reduce the prevalence of infectious diseases. Biodiversity loss is associated with increased risk of zoonotic diseases, as species diversity can influence the emergence of new pathogens. Managing biodiversity can help control pathogens, such as through the use of natural enemies or probiotics. Biodiversity loss is also linked to increased risk of drug-resistant pathogens, as reduced microbial diversity can allow resistant strains to dominate. Managing biodiversity can help reduce the risk of emerging diseases by reducing human-animal contact and preserving habitats. Biodiversity loss is a major threat to human health, and preserving biodiversity is essential for reducing the risk of infectious diseases.Biodiversity loss is linked to increased transmission of infectious diseases.
