You must read each slide, and complete any questions on the slide, in sequence.

Critical Analysis Question:

The doubling time of a population can be estimated by dividing 70 years by a population’s annual growth rate percentage. What are the estimated doubling times for the populations of Lesotho, with an annual growth rate of 0.3% in 2010; the United States, with an annual growth rate of 1%; and Yemen, with an annual growth rate of 2.7%?

To formulate your answer, first consider these additional thought questions:

  1. 1.

    What is the doubling time for a population?

    		A.
    		B.
    		C.

  2. 2.

    What is the population doubling time equation?

    		A.
    		B.
    		C.

  1. Now that you know the population doubling time equation, use the information in the following scenario to fill in the equation blanks below.

    3.

    If the global population size is 7 billion and it is growing at 1.2% per year, what is the global population's doubling time?

    		A.
    		B.
    		C.
    		D.
    		E.

Now we return to the original Critical Analysis Question: The doubling time of a population can be estimated by dividing 70 years by a population’s annual growth rate percentage. What are the estimated doubling times for the populations of Lesotho, with an annual growth rate of 0.3% in 2010; the United States, with an annual growth rate of 1%; and Yemen, with an annual growth rate of 2.7%?
