The marginal health impact of 1 ppm (of what?) may not be the same across all concentrations, not least because of adaptive behaviors: avoiding outside exercise, using air filters. But in general I agree that you should be able to look at tradeoffs of a set of actions and allow of the possibility that some negatives are offset by positives. |
