I think it's about environmental damage (I seem to recall hearing that it was about one particular polluted beach, but I could be wrong about that. In any case, the overall theme is pretty clear ("made the water turn to black", "they'd do almost anything if the price was right enough", etc). And there's also a poke taken at half-cocked wannabe activists ("I'll get my guns and both of my friends", the best line in the song by far).
