Why is it terrible? The OP said to burn what you can for electricity, so that really should just leave metals. Copper is valuable, so hopefully they'd strip all the wiring and recycle it, leaving just steel and maybe aluminum (which itself is valuable for recycling too). How is dumping steel car frames in the ocean "terrible"? These days, entire ships are sunk (after getting all the fluids out of them) to actually help the ocean wildlife as artificial reefs.

However, I do agree there should be a lot more effort to recycle this stuff.
