Morbidity and Mortality

Morbidity and mortality are the two demographic phenomena most commonly studied in epidemiology. These two phenomena allow us to view disease trends and associated changes over time.

Discuss morbidity and mortality in terms of how you would use them in developing prevention strategies aimed at increasing attention to disease and decreasing adverse health outcomes. Which phenomenon is better to study to develop preventive strategies? Why?

Justify your response using examples and reasoning. Comment on the postings of at least two classmates, explaining whether you agree or disagree with their views.

Evaluation Criteria:Discussed how morbidity and mortality would be used to develop prevention strategies aimed at increasing attention to disease and decreasing adverse health outcomes.Explained which phenomenon is better to study to develop preventive strategies and justified the answer.Justified answers with appropriate research and reasoning by using examples and references from textbooks, the South University Online Library, and other acceptable references, citing the sources in APA format.Commented on the postings of at least two classmates by asking questions, provided a point of view with a rationale, challenged a point of the discussion, or made a relationship between two or more points.

Develop a water sustainability plan for your city, hometown, or neighborhood. The plan should include sources of pollution and ways in which you plan on addressing these sources. Present your plan to the local city council.

Develop a 7-10 slide PowerPoint Presentation to present the sustainability plan. Include the following in your presentation: An introduction that identifies the main challenges of managing a fresh water resource in your home town or city. State the activities that have impacted this local fresh water supply. Include the name of the lake or river, the specific pollution sources, and the pollutants in your presentation. Describe how these pollutants have impacted (or could impact) human health, plants, and wildlife. Present a plan to clean up this pollution source, prevent future pollution, and to ensure that the water source is not overdrawn enabling long-tem use. Include specific methods from your research. Identify at least three stakeholders in your plan (community residents, local government, businesses, non-profit organizations, etc.). Describe the local government policy that you will need in order to carry out your plan. And the role of each of the three stakeholders in ensuring that the water is used sustainably. 

Use your textbook, and three additional sources. One of these sources should be an academic journal found at the University’s library. If you need assistance with identifying an academic journal article (also known as peer-reviewed articles), review the Finding Peer-Reviewed Articles document.

Include an introductory slide, a summary slide, and a reference slide.

Include 300 to 750 words in your speaker notes.

Include supporting visuals, such as photos, diagrams, and/or graphs.
