Most of the abyssal plain, I believe, does not support life. The exceptions are spreading centers (anywhere that provides heat). If stuff is weighted (even plastics), I wonder what kind of effect dumping (I'm thinking minimal, but I don't really know about the biology involved) would have at the more barren areas of the deep ocean.
Personally, I'm waiting for the space elevator / rain gun so we can toss all our trash into the sun...
Surprised that nobody has spoken up...
What do you suppose we do with garbage on a submarine?

I know that the quantity is nothing like what the surface Navy produces, but it has been going on for years. Quiet and undetected...:icon_wink
