I live a few miles from steel mills, oil refineries, who take advantage of Lake Michigan, constantly polluting both air and water, occasionally dumping/"releasing" more toxic chemicals than permitted and don't raise the alarm for a few days: https://www.in.gov/idem/cleanwater/2576.htm, killing thousands of fish, closing water intake, parts of the National Park, etc. etc.
I've lived in Gary, IN since 2016, moving from the UK. A few weeks ago, a young lad from Gary died of a really rare cancer: https://www.cnn.com/2020/11/18/us/ben-watkins-masterchef/ind...
Last week, my 3 month old daughter got diagnosed with really rare genetic disorder called Kabuki Syndrome, on top of heart disease.
Who knows if either is/was caused by living so close to steel mills and/or pollution, but I'm skeptical. Did I cause/impact/increase/etc my daughter's condition by choosing to live next to a steel mill? I just have to accept that I'll never know the answer to that question.
