What is meant by population transition? Briefly describe the recent changes in human populations and the driving factors involved.

Historically what other transitions have occurred? Is this a constant process or have there been periods with larger changes? What has the role of technology played in different population transitions?

If births (b) are influenced by population density (N) such that b = bo - b_1N, and deaths (d) by d = do + d_1N rewrite the equation for population change

dN/dt = (b=d) N

as a logistic equation

dN/dt = r N (1 - N/K).

What are the r and K terms in terms of b and d?

6) The current turmoil in the Middle East is causing sharp transitions in populations and a great deal of environmental damage. Summarize the recent history of these events and the social economic problems behind them. Include an explicit discussion of demographics of the situation.

7) The western United States is currently experiencing a prolonged drought. It is especially severe in California.Write a short essay focusing in on one aspect of the situation.
