Nature and Culture Prof. David Backes Catalog of Personal Property Our possessions have symbolic meaning, both in a personal sense and in a cultural sense. A good way to reflect on the meaning of ownership, and of our own consumption patterns, is to make a list of everything we own. And that is what you will do for this assignment. I want you to spend a few hours taking an inventory of your possessions, and making a reasonably detailed list of what you own. (If you own several dozen books, for example, write that down. But you don’t need to give an exact count, or list the titles and authors. ) Once you’ve made the list, I want you to look it over carefully, think about it, and type a page or two about the meaning of possessions in your life, now and in the future. Most of you are young enough that you don’t have too many possessions yet, but here are some questions I’d like you to think about and that may help you decide what to write about in your brief essay. • Do you think that your life would be happier if you had more money? Why? What income do you think you will need to fulfill your dreams? • Do you use student loans or credit cards to pay for things you want but don’t need? Do you worry about your ability to repay the amount you’ve borrowed? What does this say about the role of material possessions in your life? • Have you ever thought about how the things you buy and the things you do have an impact on the environment and also on the world’s poorest people? Do you think awareness of this will affect how you choose to live? Why? • To raise a similar point, but in a different way: when you are making buying decisions, do you consider whether the items are environmentally or socially friendly? Why? • Do you often feel rushed, with too much to do and not enough time to do it? How does your answer compare with your ideas about the amount of money you need to fulfill your dreams? • What’s more important to you? A high-paying job, or a job that is truly fulfilling? How does your answer compare with your ideas about the amount of money you need to fulfill your dreams? “We Americans are great on fillers, as if what we have, what we are, is not enough. We have a cultural tendency toward denial, but, being affluent, we strangle ourselves with what we can buy. We have only to look at the houses we build to see how we build against space, the way we drink against pain and loneliness. We fill up space as if it were a pie shell, with things whose opacity further obstructs our ability to see what is already there.” — Gretel Ehrlich —

According to Ishmael, how do Takers envision the role of humans “in the divine scheme?” What is humankind’s purpose? How has this perspective affected human/nature relationships? 6. According to Ishmael, how do most Takers envision the future of humanity? As part of your answer, describe how most Takers say we should deal with problems such as energy shortages and pollution. 7. What is Daniel Quinn trying to get you to perceive about the state of our culture’s relationship with nature? How does his story-telling approach affect your perception about environmental issues? To what extent is his approach successful, and why?

Sex, Gender, and Popular Culture Spring 2015 Look through popular magazines, and see if you can find advertisements that objectify women in order to sell a product. Alternately, you may use an advertisement on television (but make sure to provide a link to the ad so I can see it!). Study these images then write a paper about objectification that deals with all or some of the following: • What effect(s), if any, do you think the objectification of women’s bodies has on our culture? • Jean Kilbourne states “turning a human being into a thing is almost always the first step toward justifying violence against that person.” What do you think she means by this? Do you agree with her reasoning? Why or why not? • Some people would argue that depicting a woman’s body as an object is a form of art. What is your opinion of this point of view? Explain your reasoning. • Why do you think that women are objectified more often than men are? • How does sexualization and objectification play out differently across racial lines? • Kilbourne explains that the consequences of being objectified are different – and more serious – for women than for men.

Why is it important to look at images in the context of the culture? • What is the difference between sexual objectification and sexual subjectification? (Ros Gill ) • How do ads construct violent white masculinity and how does that vision of masculinity hurt both men and women?

ANSWER: Concept Review: Calculating Doubling Time Chapter 04 Homework http://session.masteringenvironmentalscience.com/myct/assignmentPrintV… 7 of 13 5/21/2014 7:59 PM Can you calculate doubling times and growth rates for exponentially growing populations? Remember that the doubling time (in years) for an exponentially growing population is estimated by dividing 70 by the growth rate of the population (as a percentage): Doubling time (in years) = 70 / annual growth rate (%) Part A Drag the values on the left to the appropriate blanks on the right to complete the sentences. Not all values will be used. ANSWER: Concept Review: Calculating Population Growth Rates Populations grow larger from births and immigration and grow smaller from deaths and emigration. The growth rate for a population is determined by adding the birth rate and the immigration rate, and then subtracting the death rate and the emigration rate (all rates expressed as the number per 1,000 individuals per year): (birth rate + immigration rate) (death rate + emigration rate) = growth rate Positive population growth rates lead to population increases, and negative population growth rates lead to population declines. Part A Suppose you are studying a population with the following characteristics: Birth rate = 14 per 1,000/year Death rate = 6 per 1,000/year Immigration rate = 5 per 1,000/year Emigration rate = 1 per 1,000/year What is the growth rate for this population?
