A Tale of Twin Towns
Natural Capital Degradation
Author(s)
Abstract
This case study presents the fictional tale of two neighboring towns that have recently experienced a growth boom and are now suffering the environmental consequences. The case provides an opportunity to explore a wide variety of anthropogenic causes of natural capital degradation. Students are assigned the role of scientists working for the regional Department of Environmental Resources Management, and it is their job to discover the underlying causes for a wide variety of citizen complaints and to suggest reasonable and cost effective solutions. The case may be assigned as a recap activity after teaching a unit on natural capital degradation. The case includes a PowerPoint presentation as well as three lab activities that are included in the teaching notes. The case would be appropriate for high school or lower level undergraduate ecology or environmental science courses.
Objectives
- Evaluate environmental effects of extracting mineral resources.
- Analyze the transmission of diseases via water.
- Predict the effects of acid deposition on plants and soil.
- Scrutinize the effect of human activities on the concentration of greenhouse gases in the troposphere.
- Describe and summarize the effects of various water pollutants on surface and ground water.
- Determine the causes leading to cultural eutrophication and how to reduce them.
- Explain how ground water can become contaminated.
- Explore and recommend measures to prevent ground water contamination.

- The Anthropocene: Human Impact on the Environment
Human activities are reshaping our planet in profound ways. The changes that have occurred in the last 50-200 years have led scientists to propose a new geologic epoch, called the Anthropocene. This interactive activity demonstrates how human population growth, air pollution, agriculture, mining, water use, and other human activities have impacted the environment and the mark they will leave in the fossil record.
