Biodiversity and Ecosystem Services
Biodiversity refers to the variety of life forms on Earth, including plants, animals, and microorganisms, as well as the genetic differences within these species and the ecosystems they form. Ecosystem services are the benefits that humans derive from these natural systems, such as clean air and water, pollination of crops, climate regulation, and soil fertility. Together, biodiversity and ecosystem services are essential for sustaining human well-being and environmental health.

💡 Key Takeaways
- Biodiversity covers the variety of life forms, their genetic differences, and the ecosystems they form on Earth.
- Genetic diversity within species supports resilience and adaptation to changing environments.
- Ecosystem services are the benefits humans receive from natural systems, such as clean air, water purification, pollination, and climate regulation.
- Loss of biodiversity can reduce the quality and reliability of these services, impacting health, food security, and livelihoods.
- Protecting biodiversity involves conservation, sustainable resource use, habitat restoration, and reducing pollution and climate stress.
❓ Frequently Asked Questions
What does biodiversity include?
Biodiversity includes the variety of life on Earth—plants, animals, and microorganisms—plus the genetic differences within species and the ecosystems they form.
What are ecosystem services?
Ecosystem services are benefits humans receive from natural systems, such as clean air and water, climate regulation, pollination, and recreational or cultural values.
What are the main categories of ecosystem services?
Provisioning (goods like food and water), regulating (climate, flood control), supporting (pollination, nutrient cycling), and cultural (recreation, aesthetics) services.
Why is biodiversity important for resilience?
Higher biodiversity can increase an ecosystem's resilience, helping it withstand disturbances and continue delivering essential services like pollination and water purification.
