Within the framework of marine, freshwater and terrestrial ecosystems, this course considers the characteristics of the natural environment and in particular the potential for environmental destruction. Questions such as the disposal of toxic wastes, natural hazards (landslides, volcanic eruptions and earthquakes), resource exploitation and land use planning are discussed with special emphasis, through fieldwork, on the local or regional environment. This course is specifically designed for students with little or not background in science.

Means of Assessment
|Term projects (3)
Upon completion of this course, the student will be able to:
- Show an understanding of the components and dynamics of an ecosystem.
- Show an understanding of the distinctions between major biotic and abiotic characteristics of marine, freshwater and terrestrial ecosystems.
- Show an understanding of the interaction between people and the physical/biological environment in which they live and of the problems produced by the increasing encroachment on that environment.
- Describe the geomorphological processes operating in terrestrial and marine environments and identify the more common landforms produced by these processes.
- Show an understanding of the processes involved in the exploitation of natural resources, both renewable and non renewable, and of the potential detrimental effects of such exploitation.
- Describe the problems and possible solutions associated with the disposal of toxic and hazardous wastes.
- Discuss the causes of natural hazards and their effect on the stability of ecosystems and on patterns of human settlement.
- Discuss the impact of the exploitation of various energy sources on the environment and the relative merits of alternative energy sources.
- Show an understanding of the effects of urbanization on the natural environment and of the scientific, social and political considerations required for land use planning.
- Demonstrate an understanding of the concepts described above in the context of local or regional environmental problems.
- Show an understanding of some of the potential global environmental crises.
- Demonstrate an understanding of environmental regulation.
