Agenda  What is Biodiversity?  What is Happening to Biodiversity?  Why is this Happening to Biodiversity?  What are the Effects and What do They Lead to?  What Must be Done to Save Biodiversity?  How are Scientists Doing This?  Conclusion

What is Biodiversity?  Organisms  Habitats  Ecosystems

What is Happening to Biodiversity?  Being lost  Species endangered/going extinct Disappearing 1,000 times natural rate 34,000 plants species 5,200 animal species 1/8 bird species

Why is this Happening to Biodiversity?  Deforestation - Human activities Invasive species – human & natural activites

What are the Effects and What do They Lead to?  Deforestation Loss of forests – Imbalanced air composition Loss of homes – Extinction Loss of wood – Material loss  Invasive species Take over local species – Extinction  Extinction Domino effect Loss of medicine

What Must be Done to Save Biodiversity?  Raise awareness of ways to save biodiversity  Reduce deforestation  Prevent Invasive species from being introduced to more places  Habitat conservation

How are Scientists doing this?  Raise awareness – 2010 International Year of Biodiversity Importance Threats Means of conservation  Reducing deforestation – Apple-Paper Uses apples Reduces wood usage

How are scientists doing this?(cont)  Invasive species: Chemical means ○ Many disadvantages Biological means ○ A disadvantage Mechanical means ○ Effects has a limit Ecosystem management ○ No negative effects

How are scientists doing this?(cont)  Conservation of habitats – Sungei Buloh Wetland Reserve Proposed by Malayan Nature Society (Singapore Branch) Converted into nature park

Conclusion  Do our part  Reduce, Reuse, Recycle  Save biodiversity
