|Description - |
|An introduction to environmental biology and a survey of the biological and ecological principles needed to understand environmental issues. Global, national and local perspectives on current issues such as resource use, pollution, biodiversity and impacts of human population growth.|
|Course Objectives - |
|The student will be able to: |
- describe the scope of environmental biology and its relationship to other sciences.
- describe the scientific method and explain its uses and limitations as it pertains to environmental biology.
- identify and apply basic biological and ecological principles.
- describe the history and future trajectory of human population growth.
- evaluate the implications of human population growth.
- characterize air, water and land resources, describe the threats to these resources, and evaluate possible solutions.
- characterize biodiversity, describe threats to biodiversity, and evaluate approaches to conservation.
- describe the status of food resources, including agriculture and fisheries.
- evaluate alternative energy sources.
- describe the roles of governmental agencies and non-governmental agencies in affecting environmental policy and patterns of resource use.
- discuss contributions that an individual can make toward affecting environmental policy and sustainable use of resources.
- critically evaluate media generated environmental information and contrasting viewpoints on environmental issues.
|Special Facilities and/or Equipment - |
|Fully equipped multi-media lecture room. Students need internet access. |
