learning objectives

Page history last edited by Gilberto Rosado 16 years, 2 months ago

 

 

This page provides the learning objectives for our course. It may be updated throughout the semester to reflect emerging interests of our participants or outstanding questions from our study. If you plan to lead in addressing one of these objectives, please place your name in parentheses after the square brackets with source reference. If you are able, please also the objective # to your corresponding presentation, document or wiki page you created to address this objective.

 

If you'd like to add any learning objectives you personally have for a give section, please feel free to insert and number them after the initial set. If you do, please be sure to formulate your objective in a way such that successful learning (competence) could be readily assessed or measured, e.g., "Describe what a metapopulation is and why its important to conservation." And NOT "Learn more about metapopulations" (which is not easily measured as stated). See early session for examples of "assessible" learning objectives.

 

Thank you for helping to steer this course in directions which appeal to your respective interests -- and likely those of your peers as well!

09 Session: Human Ecology (Part VIII) | 09Plan

 

Have we reached "the end of nature?"

 

"I believe that ... we have already stepped over the threshold ... that we are at the end of nature...... I do not mean the end of the world. The rain will still fall and the sun shine, though differently than before. When I say 'nature,' I mean a certain set of human ideas about the world and our place in it." [......]

 

"An idea, a relationship, can go extinct, just like an animal or a plant. The idea in this case is 'nature,' the separate and wild province, the world apart from man to which he adapted, under whose rules he was born and died." 

 

- Bill McKibben, The End of Nature (1989) 

 

For your consideration: What do you think? 
Are we now at the end of nature? 
(Or were we 20 years ago, but now "past that?")

 

Chapter 27. Population Growth, Resource Use, and Sustainability

 

09-1. Argue the relative merits and drawbacks of conventional vs. "sustainable" means for obtaining one ecosystem service discussed in our text or readings. (Ch. 27, IPCC 2007, Millennium Ecosystem Assessment) (LEAD?)

09-3. Reviewing McKibben's argument (in the box to the right) a generation ago, that "we are at the end of nature," provide a well-reasoned 21st C. counterpoint to his perspective. (Be sure to demonstrate your ecological wisdom!) (LEAD?)

 

09-4. How might we address Pauly (1990s) concern regarding Malthusian overfishing using what we now know about intra- and/or inter-species interactions? (LEAD?)

 

09-5. (student selected)

 

Chapter 28. Habitat Loss, Biodiversity, and Conservation

  

09-6. Formulate a brief habitat conservation plan of you own design (not an external source's) to protect a vulnerable [VU] or endangered [EN] species of your choice from the IUCN Red List. (Ch. 28) (JL) Jennifer-9-6-Giant Panda

 

09-7. Summarize the case made by EO Wilson (2001) in The Future of Life, both his concerns and proposed solutions, then augment this with an pertinent and well-informed idea of your own. (Wilson 2001) (LEAD?)

 

09-8. Describe how the reintroduction of an animal may be necessary to reestablish a declining species' population. (KH)

Chapter 29. Global Climate Change
