Today's Knowledge: Global Warming and Worker Safety

I don't mean to be a bummer on the Fourth of July, but whether we are hanging out at cookouts and shooting off fireworks or not - there are serious and grave issues that still surround us. Listen to and/or watch this Bill Moyers episode that covers both Global Warming and Worker Safety. Grim - yes. Important - definitely. My hope is that reporting like this will reach and infuriate the masses.
