Course Details

Course
Description
For this course, human-caused ecological catastrophes are defined as slowly developing, negative environmental changes that were caused at least to some degree by human actions. They were widespread spatially and long-term temporally, and they impacted society greatly.

Five past catastrophes in US history of particular note ("Great") will be covered in depth:

  • Dust Bowl
  • Eradication of the Passenger Pigeon
  • Wholescale Alteration of Forest Fire Across Western Forests
  • Loss of Perfect Trees: The American Chestnut and the American Elm
  • Mobilization of Lead (Pb) in the Environment
One modern-day issue will also be analyzed for its potential to become an environmental catastrophe:
  • Global warming
Two principal methods of teaching/learning will be employed in this course:

  • Strategically reading non-fiction sources, including whole books, popular magazine articles, and scientific journal articles
  • Making videos (fear not, everyone can do this, it's not hard)

Instructor Paul Sheppard, Assoc. Prof. of Dendrochronology
407 Tree-Ring Building, 621-6474, sheppard @ ltrr.arizona.edu

Prerequisites Upper-division (junior or senior) standing
Tier 1 and Tier 2 Natural Sciences completed

Course Objectives
  • Become aware of selected past human-caused ecological catastrophes in US history
  • Quantify ecological catastrophes in terms of geographical extent, temporal length, intensity, and societal impact
  • Compare and contrast the modern-day issue of global warming with those past ecological catastrophes
  • Read extensively on one past ecological catastrophe, including at least one non-fiction book
  • Read more generally on all selected ecological catastrophes, including articles from lay magazines as well as scientific journals
  • Develop video production skills, including displaying movies and still images, adding text and narration, and including music
  • Collaborate in small groups to produce a 5- to 10-minute video on one of the selected ecological catastrophe
  • Peer review the videos produced by fellow students on the other selected ecological catastrophes

Course Outcome This course will serve as an upper-division elective for majors in History, Environmental Sciences (Soil, Water, and Environmental Sciences), and Environmental Studies (School of Geography and Development)

  Late work will be accepted, but will be graded down according to how late it is.

Examinations There will be no exams in this class.

Fieldtrips For each selected ecological catastrophe, a short trip in and around Tucson will be taken. Each small group will take only the trip relevant to their chosen catastrophe:

• Dust Bowl: A local farm to view arid-land agriculture and dust abatement measures, and interview an expert
• Passenger Pigeon: International Wildlife Museum, to see a mounted Passenger Pigeon, and interview an expert
• Forest Fire in the West: Mt. Lemmon, to see burn area of the 2003 Aspen Fire, and interview an expert
• Loss of Perfect Trees: Reid Park, to see Aleppo pines, and interview an expert
• Lead in the Environment: An EPA air monitoring site for airborne lead, and interview an expert

Transportation will be provided using UA vehicles. A student course fee of ~$10.00 will cover the vehicle expenses.

Attendance and Participation Attendance in class will be recorded and active participation in class will be expected.

Absences for sincerely held religious belief, observance, or practice will be accommodated where reasonable.

Absences pre-approved by the UA Dean of Students (or dean's designee) will be honored.

Readings and Texts No single textbook exists for this course, but this course will be reading-intensive. Students will be expected to read at least one book on the ecological catastrophe chosen to study in-depth. These books are easily and economically obtainable on-line.

Students will also be expected to read many shorter articles on all five ecological catastrophes. These articles will come from popular lay magazines as well as scientific journals and will be made available from this course website as password-protected pdfs.

Special Materials Producing videos requires software dedicated to this task. The UA provides all students access to the Adobe Suite, including the video software that will be used in this class. It is free to download, and it is also installed and freely accessible on computers of the UA Libraries.

Conduct
  • Adhere to the ABOR code of conduct and the UA Code of Academic Integrity.
  • Adhere to the UA Threatening Behavior by Students Policy prohibiting threats of physical harm to any member of the University community, including to oneself.
  • Adhere to the UA Policy creating and maintaining an environment free of discrimination and harassment.
  • If you must arrive late or leave early (something not encouraged), please do so quietly.
  • If you have a phone (who doesn't?), please turn it off during class. If you must talk on your phone (does anyone talk on the phone anymore?) or text message someone during lecture, please do that outside of class.
  • If you must read the newspaper (anyone?), tackle the Wildcat crossword and sudoku puzzles (anyone?), study for other courses (occasionally), sleep (lots), surf the web, update Facebook, Farmville, shop Ebay, play online poker, watch DVD movies, binge watch Thrones, or do anything else not related to this course during our lecture time, please do it elsewhere, not in class. These activities are obvious (click here for an example) and are officially considered disruptive. See here for a UA student opinion about surfing the web in class.
  • Click here to see research saying people who multitask really aren't good at multitasking.
  • Racism, sexism, or violence will not be tolerated in the classroom.
  • It's acceptable—even encouraged—to collaborate with fellow students in this course. However, cheating will not be tolerated, including but not limited to:
    • Copying work of fellow students.
    • Plagiarism (click here for a definition of plagiarism).
  • Special note on plagiarism: Some definitions of plagiarism imply that all that is necessary to avoid it when copying someone else's text is to put it in quotes and then cite the original source. While technically this may be true and acceptable in some academic settings, copying someone else's text (put in quotes or otherwise) is hereby NOT acceptable in this course. This includes text from fellow students or students from past semesters, published articles or newspapers, and web sites. In short: Citing yes, copying and/or quoting no.
  • Another note on plagiarism: If you'd like a fictional account of plagiarism, try Stephen King's, "Secret Window, Secret Garden," definitely a horror story. The movie adaptation, "Secret Window" with Johnny Depp and John Turturro, was good, too.

Special
Provisions
  • In compliance with Title III of the Americans With Disabilities Act (1990), students who require special assistance will be suitably accommodated. Students must be registered with the University and a minimum notice of 5 days for such accommodations is requested.
  • Students requiring special accommodation: Please notify the professor and provide the Disability Resource Center letter within the first few days of the course.
  • Student athletes and others who need signatures periodically: Please notify the professor that you'll be needing signatures generally, and please alert the professor before a particular signing period is due so that your most up-to-date grade can be calculated.

Subject to Change Information contained in this course syllabus, other than the grade and absence policies, may be subject to change with reasonable advance notice.
