Part 2 – In Depth

Choose from one of the following prompts to complete.

Select one of the prompts below to research further (see Resources on Blackboard for some links to try). Address the prompt with a short essay (2-3 paragraphs) that includes at least one valid unbiased source from a scientific or social journal or site (cited in APA format).

1. Population growth in developing countries is happening at a rapid pace. Do you think that it is appropriate for developed countries to persuade less-developed countries to limit their population growth? What might be appropriate and inappropriate interventions? Find a source to support your response.

2. The U.S. government has eased up on restrictions put in place that govern the coal mining industry. Find a recent article (within the past 3 years) that discusses the environmental and economic issues associated with coal mining. Summarize the article and share your opinion on the issue.

3. Wind farms have been proposed for various coastal areas in the region, including off the coast of Ocean City, Maryland and in the Chesapeake Bay. Research this issue and report on what proposals are being contemplated and whether they are moving forward or not. Also address the following:

a. Are these proposals economically feasible? What impact would wind farms have on the environment?

b. Should private citizens have a voice in whether wind farms are built and where they are built? Or should such decisions be left to the government?

c. What are your views on this issue?

You must reference an appropriate scientific resource and include the APA citation.
