Reminds me of a movie I saw as a kid where a guy from the future comes back to the 80s. There's a scene where he's looking for new batteries for his gadgets. Woman at the store counter (peering suspiciously at the battery): "What kind did you say they were?" Traveler: "Plutonium." My only thought at the time was "My god, what an ecological nightmare that would unleash when people start throwing these things out with the trash!"
