Rusty
People who lived in or built civilizations out of metal or with metal skeletons.They also cut down trees and/or forests to make way for more buildings. They overproduce and polute the air we breathe. (Mainly us.)Rustys are concidered not very smart or very aware that what they do is distroy their world they live in and the world that generations to come will have to live it. They are ignorant and selfish. They are wasteful.

"Remember what I'm telling you. This is for your own good. You don't want to end up like those Rustys who almost destroyed the earth with their polution and tree cutting. "
