Why is low biodiversity bad?

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 advantages of low biodiversity?

Why the biodiversity is important?

Diversity in all living things enriches our lives, but more importantly, biodiversity is essential to life on earth. Biodiversity not only maintains a functional environment; it is a resource for food, shelter, clothing and other materials.

What happens if we lose biodiversity?

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.

Why is biodiversity a problem?

Biodiversity loss disrupts the functioning of ecosystems, making them more vulnerable to perturbations and less able to supply humans with needed services. … To stop ecosystem degradation, the full contribution made by ecosystems to both poverty alleviation efforts and to national economies must be clearly demonstrated.
