Smoke from wildfires

Smoke from wildfires harms people even thousands of miles away. A small concentration harms a smaller number of people but isn't harmless.

Since even wealthy people don't know how to protect themselves, we should have programs that aim at protecting everyone. Or perhaps everyone with asthma, if only people with asthma are particularly in danger.

In the long run, we can expect wealthy people to pay for this protection themselves, once we make sure they know what is needed.
