Kluthe - 1/23

In my environmental science class, we've been discussing the problem of human population growth. Students have been using the obituary section of the KC Star to collect longevity data on people in our area. They have been calculating average lifespans of people born in different decades and graphing survivorship curves of men and women. They've been asked to apply what they know of the time periods to try to figure out why the numbers came out like they did.
