Surf the Internet and find hope. I just found the Campaign Against Depleted Uranium. They are trying to make a stand against the use of DU in many areas, but the one which concerns me, obviously, is America's use of DU to wage nuclear war against Iraq (and Afghanistan, and...). This is not a republican-democrat issue, though: apparently we used DU in the Balkans, too. War is horrible no matter where it comes from, and both political parties in America are guilty of waging it.
An important article describing DU can be found here, and another site with information can be found here. There are a lot more, of course. The world needs to be reminded: we are waging nuclear war.
