I did an internship at a pulp mill that was on the Canada-U.S. border (Canadian side). There was an elementary school literally besides the plant (~50m away).

I did an internship at a pulp mill that was on the Canada-U.S. border (Canadian side). There was an elementary school literally besides the plant (~50m away). If there was a release of sulphur dioxide that was going to stay on the Canadian side, the plant management notified the relevant authorities. Sometimes the kids were told not to go outside for recess. If the SO2 was potentially going to drift over the border, the entire plant was shut down because the U.S. EPA would hit them with millions of dollars in fines. Was someone talking about ethics and morality?
