Preparation
Watch: (https://www.youtube.com/watch?v=9GorqroigqM). Taking notes is recommended, and it may also be helpful to read through the discussion questions before watching the video.
Procedures
Choose one of the following questions and post a thoughtful paragraph on the course discussion board. Thoughtfully engage the material–at this point you should be able to make connections between various aspects of course material. Cite the video and any other aspect of course material from any week thus far! Please be specific, and use examples whenever possible (real life examples are great).

Ecology is the way that species interact with their environment. How does our materials economy relate to human ecology, and what are some of the consequences of these systems?
Why cant a linear system work indefinitely in a finite world? What are the alternatives? In what ways can we increase public awareness of our ecological footprints? Use specific examples in your answer.
Which people, or which populations, are most negatively affected by the materials economy described in the video? What does this tell you about global social hierarchies, or human social stratification? Is there justice in this system? What can be done to change it? What are some effective ways to reduce material consumption in everyday life while maintaining livability?
What does the materials economy have to do with human evolution? Did waste exist before humans appeared? In other words, relate the main points of the video to overall themes from this course.
What is the problem with the $4.99 radio? Who pays?
Your stuff, my stuff, our stuff. What is it, where does it come from, who pays for it, with what currency, and where does it go? Why do we want it or need it, and is it really worth the cost?
Through advances in technology can we significantly reduce our impact on the environment in the long run, or are we reallocating our ecological impact? Do you agree that sustainable interaction with ecosystems is only possible if demands are kept within bounds? Why or why not?
Discuss an example of a technology that enhances sustainability. Consider its systemic effects on the environment.
