1. Compile a list of families you know ell. What is the average number of children per couple? If this were the average for the world population, and if all the children survived, what would be the doubling time of the population? Use a graphing paper and assume 30 years as a generation, refer to the table below. 2. Collect new paper clippings on the effect of population on natural communities, study the articles again for evidence connecting the population explosion with pollution of the environment. Do you find any evidence that the population or pollution problems are being solved? The relationship between growth and doubling time Annual rate of growth (percent) Doubling time (years) 140 0.5 1 2 3 4 5 7 10 70 35 23.33 15.5 14 10 7 The general rule of thumb is to determine the doubling time, divide 70 by the growth rate. Conversely, to determine the growth rate, divide 70 by the doubling time. This rule will work for growth rates and doubling times that you are likely to encounter in…
