Presentation transcript:

Biodiversity *the last set of notes I will give as a classroom teacher* Targets: 10. Explain the importance of biodiversity. 11.Describe the four main threats to biodiversity. 12. Describe four approaches to conserving biodiversity.

What is biodiversity? Biodiversity can be measured in several different ways – Number of species in an ecosystem – Variety of ecosystems in the biosphere – Genetic variety among individuals within a species

Why is biodiversity important? Ecological value…interconnection of life Intrinsic value…beautiful and inspirational Economic value…source of food, clothing, shelter, and medicine

What are the main threats to biodiversity? Habitat destruction and fragmentation Invasive species Overexploitation

What are four ways we can conserve biodiversity? Focusing on Hot Spots Understanding an Organism’s Habitat Balancing Demands for Resources Planning for a Sustainable Future – Zoned reserves – Buffer zones – Sustainable development
