There is no threshold level of fine particle pollution below which health risk reductions are not achieved by reduced exposure.
The risk of pollution exists for the infosphere as it does for the atmosphere. Freedom of the infosphere should thus become a law, and the Bible needs to have an 11th commandment: Thou shalt not covet thy neighbor's data.
If you drill, there's going to be a spill. It's axiomatic.
