BIODIVERSITY:Extinction and
Measuring Population Density
OBJECTIVES:1. Identify the causes of extinction and explain how it is done.
2. Determine the pattern of population distribution using mathematical formula.
3. Compare the distribution patterns of the different populations.
4. Read selections about phenomena that are related to biodiversity and define the words that will be cited as to how they were used in the selection.5.Write a reflection paper about the video on protecting biodiversity.

WHAT CAN BE DONE?
BIODIVERSITY LOSS
Every species are important!
BIODIVERSITY LOSS
But their homes are wrecked, leading them to deaths.
BIODIVERSITY LOSS
What can people do to protect biodiversity?
BIODIVERSITY LOSS
1. PROTECTING AREASCreating protected areas where human activity is limited is the best way to prevent deforestation and exploitation of organisms and the resources they need to survive.
2, PREVENTING SPECIES INTRODUCTION
It is often much easier and less expensive to prevent a problem from developing in the first place than to try to fix it once it occurs!
BIODIVERSITY LOSS
3. INFORMING/ EDUCATINGEducation is a powerful tool, and the more people know about biodiversity loss, the
more they will be prepared to help slow it.
4. SLOWING CLIMATE CHANGEAny efforts as individuals, organizations, or
governments, to slow current human-caused global warming is a step towards
slowing biodiversity loss.
