This paper is written in response to the assigned readings on sustainability:

Topic:

Using at least two of the readings noted above (I suggest “Sustainability” on pages 602-608 in conjunction with another of the essays), write a proposal in which you first define a problem relating to food and sustainability and then offer a solution to it. For example, you may wish to take a stand on the issue of genetically modified foods in the United States or you might wish to examine the strengths or weaknesses of the local food movement.
