Since this is a science course, you are required to add citations and references to all initial discussion postings to show your research. These in-text citations and references are required because many of the discussion topics are NOT common knowledge. These are complex environmental science topics, and since you are studying this field, it is necessary to research your ideas and comments and back them up with citations and references. If you do not have references and citations via APA 6th edition format, your postings will be deducted points. The APA Style Guide is found on the Course Menu.

As part of substantial participation efforts the following minimum is required for each discussion:

  • APA style guide is used for all discussions and responses.
    • In-text citations and complete references
  • 200 words is required for your initial posting.
    • Please check your spelling and grammar before you post to the forum in the Discussion Board
  • Check for comments to your initial response and answer any questions or comments
  • 100 words is required of each peer feedback posting you offer to your classmates
    • You must site your references here also, following the APA formatting.
  • Offer feedback to at least two (2) of your classmates.
  • Do not limit your responses to just one day of the week, go to the discussion board several times during the Lesson week and post to the threads of your classmates with valuable information that will extend the conversation in an academic manner.
    • Be respectful as you offer constructive, non-negative responses to your classmates.
    • Never use bad language. Even if it is normal for you, it is NOT allowed in this class.

I look forward to your input on these topics and I know your classmates will too.

Lesson 3 Discussion Board

Research two developing nations’ human population growth issues.

Address the following in your first posting:

a) Do you think that all of today’s developing nations will complete the demographic transition and come to enjoy a permanent state of low birth and death rates?

b) What are some ways in which developed nations can stabilize their population growth in a sustainable manner?

c) Do more affluent nations have responsibility to help under developed nations stabilize their population growth? What are some steps that European and North American nations may take to assist the demographic transition of developing nations?

d) Provide current research that exemplify and support your analysis into this week’s exploration of population growth and transition issues.

Lesson 4 Discussion Board

People in developed nations are fond of warning people in developing nations to stop destroying rainforest. People of developing nations often respond that this is hypocritical, because the developed nations became wealthy by deforesting their land and exploiting its resources in the past. What would you say to the president of a developing nation, such as Indonesia, in which a great deal of forest is being cleared?

Lesson 7 Discussion Board

In this discussion, let’s explore traditional energy sources versus alternative, renewable energy sources.

What impacts might you expect on your lifestyle once our society arrives at peak oil?

What steps do you think we should take to avoid energy shortages in a post-peak-oil future?

Which type of alternative energy sources should our nation consider and promote? Is it possible to transition to purely renewable energy sources? What are the implications and hidden costs of using renewable energy sources?

Research at least 2 different energy sources that the USA have successfully implemented and share the pros and cons of these energy sources. How can the USA improve on the technology to harness and deliver these energy sources on a national level and reduce dependency on traditional energy sources?
