As an individual, at least you can make the argument that your activities result in far less than one death. What’s the appropriate punishment for one micromort? I don’t know the answer to that but it’s probably not too much.

Large polluters don’t have that excuse. I recall that diesel hate alone resulted in dozens or hundreds of excess deaths. How many people do compliant cars kill? How many does a coal power plant kill? And all 100% legal.
