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.
Mostly the second point. I would wager from experience that the majority of small man-portable conveyances that wind up at the bottom of lakes and rivers are there because they were stolen and thrown there. Bikes, motorcycles, rental scooters, shopping carts, etc. The reason is hooliganism, and the contributing factors are alcohol and teenagerhood.
Just for the record, teenage hooligans-in my experience -are actually preferable to the adult hooligans.
Seriously. Teenagers might get drunk and do stupid shit but they’re scared of getting caught and run away. Many times they’ll even clean up after themselves if you’re not a total dick.
Adults tend to stand their ground and pick fights.
(Also, every demographic you care to name steal shit. Sobriety, income, race. None of it matters.)
