Project #86352 - No title requires

Note: Post here only after you have read at least Chapters 8, 17, and 18 and watched the population videos.  This discussion requires multiple posts and that you read what other people write.  The best strategy is to check in periodically and not wait until the last minute to participate.

Consider the demographic transition graph in Chapter 8. The graph shows trends in three things: total population, birth rate, and death rate. This is a typical pattern of change followed by any human society as it changes from an agriculturally-based (“less developed”) economy to a more industrially- and technologically-based (“more developed”) economy. (Note that this assumes that in-migration to and out-migration from the society are not significant or that they balance each other.) In each stage, the relationship between the birth and death rates determines what happens to the population. Take some time to understand this relationship. Look at the line for population in each stage. Is it increasing, decreasing or staying the same? What is happening to the birth and death rate lines during that period?

 Transitions from one stage to another happen when social or environmental conditions change and lead to changes in birth and death rates. For example, birth and death rates change when people have more or less access to things like health care and family planning, education (particularly for women), economic opportunities, and clean water, food and other basic survival needs.

 

Imagine that you have control over social conditions on an isolated island (or planet) with a similar climate and agricultural potential as the American Midwest. The population is in the early part of the demographic transition process (Stage 1). The environmental resources are such that they can provide food for a population greater than the current population, but not enough for the population projected in Stage 4. Agricultural resources would only be enough for a population about halfway between the Stage 1 level and the Stage 4 level.

 

Given your understanding of the demographic transition graph and what you read in Chapters 8 and 18, discuss what you might do to keep the population sustainable in the long run.

 

For full credit for this discussion write a thoughtful post (see rubric for grading criteria), read the other posts, and reply to at least one other post.

  1.  In your post:
    • first explain what you think would happen if you did nothing to intervene; then
    • describe what, if anything you suggest doing to promote long-term sustainability and why.
