- Abstract:
Examines the urban environment as a natural phenomenon, human habitat, medium of expression, and forum for action. Subject has two related, major themes: how ideas of nature influence the way cities are perceived, designed, built, and managed; and how natural processes and urban form interact and the consequences of these for human health safety and welfare. Description from the course home page: This course explores the urban environment as a natural phenomenon, human habitat, medium of expression, and forum for action. The course has several major themes: how ideas of nature influence the way cities are perceived, designed, built, and managed; how natural processes and urban form interact and the consequences for human health and welfare; how planners and designers can shape the urban natural environment. Each student researches and presents a case, either historical or an example of contemporary theory and practice.

Highlights of this course include: Major biological, chemical and physical components of the agricultural systems The scientific basis for understanding these systems and their management How has science influenced policies related to agriculture, food safety and environment in the United States? How have the policies evolved over time in the US? What has worked and what has not; what are the reasons and what are the consequences? Beyond science, what other factors influence policies? How do we link what we learn to ecological agriculture? How do we use what we learn for policy analysis?

Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers help us stay healthy by designing machines and medicines that support respiratory health and function.

- Abstract:
In some cities, especially large cities such as Los Angeles or Mexico City, visible air pollution is a major problem, both for human health and the environment. A variety of sources contribute to air pollution, but personal vehicles account for one of the main sources. Though each car has relatively low emissions when compared to vehicles of the 1970s, there are so many more cars on the road now that their emissions play a large role in overall pollution. In this activity, students think about alternate ways to power a vehicle to reduce emissions. Student teams design an eco-friendly car using the engineering design process, and make a presentation to showcase their product.
