How does loss of biodiversity affect humans?

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

What are the challenges of biodiversity?

The key pressures driving biodiversity loss are overexploitation of species, invasive alien species, pollution, climate change, and especially the degradation, fragmentation, and destruction of habitats (7). Agriculture is an expanding land use in about 70% of countries (32), generally at the expense of biodiversity.

What do you mean by threats to biodiversity?

Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race. As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural ones.

Why is biodiversity in danger?

Biodiversity is subject to many threats. The greatest is probably habitat destruction and fragmentation. But there are many other threats to biodiversity. Over-consumption by humans –by hunting, fishing, or collecting from the wild– threatens many species.

Furthermore, there are myriad phenomena that are driving biodiversity loss in addition to climate change. Other causes include ecosystem fragmentation, invasive species, pollution, oxygen depletion caused by fertilizers running off into ponds and streams, overfishing, human overpopulation, and overconsumption.

Why is biodiversity important 5 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.
