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.
So much this, in NYC (less available now since Covid), there are dump sites for all this stuff (Batteries, Paint, Heavy Metals) as long as its personal amounts (ie cant come with a dump truck) it is at no cost. If you are a business and can not handle disposal fees, well you are unsustainable and should not exist.
