7. Values of Biodiversity
• Biodiversity provides excellent conditions for
and drives the processes that sustain species
survival.
• Biodiversity provides for ecological, economic
and cultural values to the world’s community.
• Climate change is changing species distribution
through shifting habitat, changing life cycles,
and development of new physical traits,

Values of Biodiversity
• People need ecosystems for adaptation and
ecosystems need people.
• Biodiversity plays a major role in meeting human
needs directly while maintaining the ecological
processes upon which our survival depends.
• Biodiversity is a national asset and a powerful
contributor to economic development, provision
of natural resource, ecological processes, and
improving human wellbeing.

10. Effect of Climate Change on Species: A case
study
• Higher temperatures speed up
reproductive cycles
• Fewer cold snaps that kill
beetles.
• Drought weakens trees, making
them more susceptible to
beetles.
• Dense older forests are more
susceptible to beetle outbreak.
Mountain pine beetles are
1/8” to 1/3” long.
Little insect – big impact.

11. ‘‘Impact of climate change on biodiversity
• Species extinction
20-30% of species at risk. • Climate change and forests
Climate change and water

12. Climate change and polar
regions Climate change and wildlife

13. Temperatures will continue to rise
Frost-free season (and growing
season) will lengthen
