Impact of Diversity: Extinction/Extirpation

US Population Explosion

This reading introduces how one country's population has changed over time. Students will discuss what the causes of this change are and what are possible ramifications? Are we seeing any issues arising currently from North America's population change?

Human Population Growth Curve

Students make a population growth curve as a class.

Discussion points include Interpolating Data and Extrapolating Data ... If we add in current world population, how accurate was this prediction?

Diversity Impact Assignment I

Scientists believe that there were 5 mass (huge) extinctions on earth! On a Google Doc:

  1. List the year that scientists believe that each extinction occurred
  2. List the evidence supporting that there each mass extinction occured
  3. List the reason(s) that they occurred and classify each reason as biotic or abiotic
  4. Submit in Google Classroom.

Diversity Impact Assignment II

The terms Extinct, Extirpated, Endangered, Threatened, Special Concern, Not at Risk and Data Deficient, are used by COSEWIC (Committee on the Status of Endangered Wildlife in Canada).

  1. Define each of the terms above in your own words.
  2. Based on the area that you will be building your house in, pick a species that fits one of the terms (Extinct, Extirpated, Endangered, Threatened). Keep in mind every country does NOT have a committee devoted to classifying each species into one of categories given! You may need to do some extra digging!
  3. Refer to the assignment details in the link (click on Diversity Impact Assignment II)
