1. IBM is paying millions for cleanup efforts. They're installing air cleaners on homes and pumping contaminated groundwater to the surface for safe disposal. An IBM spokesman said this about the toxic pollution, "None of it was done intentionally, but we still are sticking around to take care of it. We feel obligated legally, ethically. We are not going anywhere."

A. Make the ethical case that those who contaminated the environmentIBMshould pay all the cleanup costs.

B. Make the case that those who benefit from a clean environmentthe locals who work at the company and those who don'tshould pay for the cleanup.

2. When the extent of the environmental pollution became clear, it was also evident that the cleanup would be tremendously expensive. In general terms, how could a cost-benefit analysis be mounted to decide between going forward with the environmental cleanup or closing the factory, shuttering the town, and moving on?

Thank you in advance.
