No offense, but to me I interpret your perspective as: "People with stuff to get rid of tell me its good to dump it in the ocean. They said it's a good thing, so I take their word for it without critically analyzing its actual environmental impact-- plastics, metals, chemicals used in subway cars or vehicles... hey, they said it's ok, so it must be ok!"

I ain't buying it :D But then again I am an environmentalist & conservationist-- I am concerned about the apparently infinitely growing ubiquity of synthetic chemicals, due to aforementioned actions mentioned and the apparently common lack of objection (if people are even aware it is happening).
