Relative to risks I face by smoking, living next to a toxic waste site may not be very risky. In the former case, I choose to take the risk and I can take steps to minimize or eliminate them. In the latter case, I cannot avoid the risks if I want to keep my job, and very often someone else can minimize or eliminate them but this other party has a financial incentive not to do that. Surely we need another approach to workplace health and safety.
