Here's another way to look at mercury. It is a naturally occuring element that is dug from the ground. Why do so many people get upset when someone puts a miniscule amount into a landfill? If you a worried about a few contaminats then maybe we should stop driving our cars as well because they run on a naturally occuring liquid as well. It is probably a good lob that JBL didnt use mercury in any of thier products.
