Actually, it has been proven that a duck's quack actually does have a physical "echo", it's just inaudible to human hearing.

Perhaps it is the sound of one hand clapping?

Due to the rapid advancement in technology, electronics equipment is experiencing increasingly shorter periods of "useful-life." This has resulted in a surplus of Electronic Waste that, unfortunately, gets dumped into landfills releasing toxic chemicals into the soil or shipped to third world countries for disposal. Electronic waste are very dangerous our environment. You can easily repaper or reuse this.-*-
