“Waste in general is not holy”
Really irrelevant to this debate. It exists, whether it is holy or not.
“One may never see the waste in the ocean, but it can become him. That sounds crazy but it isn’t. Pollutants get absorbed in the muscle fibers of fish.”
I am not a fish, and it is unlikely that a significant amount of that pollution will end up in any fish that I, or anyone else, eat.
“We are not living in a perfect world, nor are we meant to. Nevertheless, that does not exempt us from being socially and environmentally proactive. Does it?”
Well if we were never obligated in the first place, then we are exempt, ipso facto.
Again, most, if not all, of the sources you brought discuss the prohibition of bal tashchis. You haven’t brought any sources extending that prohibition to a prohibition against damaging the environment as a whole.
I would also like to point out that bombarding me with the footnotes from articles that you read is not an effective way of winning this debate. All you need is one solid source supporting your stance.
