This case by Anthony Wilbon, Mark Bundy and Kelton Clark is designed to illustrate issues and problems in sustainability-driven entrepreneurship in the Maryland oyster industry. This once-thriving industry has been decimated in recent years by the degradation of the Chesapeake Bay's water quality, which has all but destroyed the oyster population. Small businesses must find solutions to ensure their survival. The case examines economic concepts related to environmental management. [PUB ABSTRACT]
