I agree that health matters and I think it's terrible the tournament continued when the AQI was at an unsafe level. However, this article is pretty worthless. It points out that 29 people have died, but none of them have died from the effects of pollution. They died from actual fire blazes in their direct path (e.g. firefighters, people trying to protect their homes & animals), trees falling on them, cars rolling over on them, etc. There's no danger of these types of deaths at the AO. Unfortunately there's not much info about long-term effects of short-term poor air quality exposure. I'm sure that particulate matter in the lungs does increase the risk of cancer but to what degree is unknown.
