I have been watching magnet fishing and people love to toss stuff over bridges without a second thought on the environmental impact. Hiding evidence I can almost understand but not lawnmowers, car batteries, etc.
It seems deeper fines should be made to discourage this terrible behavior.
I see answers for why people dump junk, but not why they dump it on rivers/lakes in particular.
To remedy that: dumping junk isn’t legal, and water is good at hiding things. If someone leaves their TV out on the street or whathaveyou, it might be traced back to them, but that’s less likely in a river.
