Explain the link between biodiversity loss, ecosystem services, and human well-being.

Explain the link between biodiversity loss, ecosystem services, and human well-being.

• A. Biodiversity loss reduces ecosystem services (pollination, water purification) that support food, health, and livelihoods, impacting well-being.
• B. Biodiversity loss increases ecosystem services.
• C. Biodiversity loss has no effect on human well-being.
• D. Biodiversity loss only affects wildlife.

Answer: (A)

Biodiversity underpins a wide range of ecosystem services—benefits that people receive from ecosystems such as food production, clean water, climate regulation, disease control, pollination, and even cultural and recreational values. When biodiversity is lost, the capacity of ecosystems to provide these services declines, which can threaten nutrition, health, income, and security. In turn, that affects human well-being, since people rely on these services for daily needs and resilience to shocks. For example, many crops rely on animal pollinators; when pollinators decline, crop yields and farmer incomes can fall. Wetlands and forests help filter water and reduce flood risks, protecting health and lowering costs for water treatment. A diverse ecosystem also aids in regulating pests and diseases and offers recreational and cultural benefits that support mental and social health. Thus, the statement that biodiversity loss reduces ecosystem services that support food, health, and livelihoods, impacting well-being, accurately reflects how biodiversity supports human lives. The other ideas—biodiversity loss increasing services, having no effect, or affecting only wildlife—miss the essential link between ecosystem diversity, the services people rely on, and overall well-being.
