Both water and soil are integral to human livelihood, and both are currently under threat. This class presents an overview of the issues related to water and soil sustainability including soil development and management, the hydrologic cycle, the cycling of nutrients through both soil and water, soil and water pollution, and food security related to soil and water issues.

Everyone who considers themselves an environmentalist has opinions on which sources of energy are “bad” and which are “good,” but what does that mean? How are these forms of energy harnessed by people, especially in the U.S., and how exactly are they good or bad? This course explores those questions, considering “cradle-to-grave” issues ranging from extraction of energy resources from the environment to pollution from emissions and disposal of wastes.

This course is designed to immerse students in the practice and discussion of creative writing in a marine context. For four weeks, we will live and write on Catalina Island. Classwork includes but is not limited to: whale-watching, tidepooling, poetry recitations, guest lectures from professional scientists and poets, film screenings, workshops, and generative writing exercises. We spend about half of our time “in the field,” gathering observations and notes for our creative work, and the other half discussing craft, process, and product. Readings are designed to supplement our writing practice by generating questions about the interdisciplinary capacity of language and written work as it relates to marine science, ethics, environmental conservation, and art.
