ECS 111                                                                                                          November   2016

These are suggested homework.  You may also choose any of the articles introduced in class as a review topic.  As discussed in class, you should not try and answer all of these. Choose one or two and do a complete essay on them. References should not be random blogs, but juried articles or news items from archived media such as NYT or the Economist. 


2) Describe one of the major biomes found on earth. Include a discussion of its primary physical and biological attributes. 

3) Compare and contrast two of the types of soil profiles discussed during the class. Discuss their distribution and the role they have in maintaining their associated ecosystems. 

4) Discuss von Humboldt’s observation that the different biomes seen as one goes from the equator to the poles are also found with altitude in mountain systems. Why does this vary depending on which side of the mountain range is considered?  Provide some examples. 

5) Consider the following population equations. 





Compute the steady states and discuss them. What type of system is this?

6) Discuss the immigration issues currently facing the European Union. How are these being handled by the various member states?  Is this a threat to the EU itself?  What are the consequences of these demographic shift in the Middle East?

7) Write an essay on the use of fire by human cultures.  You might approach this broadly or focus on a particular culture such as the native Americans or the bantu of Africa.

9) Consider a form of energy. Discuss the history of its exploitation and future use.

12) Read the section out of Keohane and Olmstead (2016) on competitive markets (pgs 70-78). Choose a commodity such as the one they use, coffee, and discuss the nature of the global market. 

13) Using the principles in question 12) discuss the concept of competition in energy markets. How does this change if one is considering transportation costs versus electrical power? (Note: here you might peruse the index for energy topics they introduce. The section of scarcity starting on page 100 is also a useful place to start.)

14) Consider the Keohane and Olmstead (2016) treatment of the economics of habitat management as it pertains to implementation of the Endangered Species Act. See their pages 224-230.

15) The common cold is a malady the effects humans through the world. It is associated with various viruses that all lead to a definable set of symptoms involving the upper respiratory track.

16) Discuss the sustainability of the fossil fuel industry and the problem of their use as we move into the future.

17) Produce a simple editorial style essay on the possible impacts or future climate change on agriculture. To focus you essay, you might restrict yourself to on agricultural sector, such as grains, fisheries, or meat production.
